A Biblical Frame: Current Events in Perspective

As promised some months ago, we would like to talk about the non-negotiables for the church in the world today. Many cultural movements of late have put the church in a variety of interesting positions. In this episode, Rev. Dr. Ed Gerber, Prof. Douglas Farrow, Dr. Jens Zimmermann, Dr. Aaron Kheriaty, and Ivan deSilva put forth their ideas of the church’s non-negotiable and have discussion. What are the non-negotiables for the modern church? Join us as we tackle this issue from both a Catholic and Protestant perspective. Our hope and prayer is to build up and exhort Christ’s church to be faithful in her ministry amidst todays cultural and political waves.Thank you for tuning in to this episode.Hosts:Ivan DeSilva, MDiv, ThM, Instructor in Religious Studies, Trinity Western University, Pacific Life Bible CollegeJens Zimmermann, PhD, JI Packer Chair of Theology, Regent CollegeDouglas Farrow, Professor of Theology and Ethics, McGill UniversityAaron Kheriaty, MD, Fellow and Director of the Bioethics and American Democracy Program at the Ethics and Public Policy Center.

One of the things that the Bible talks about over and over again is that when it comes to matters of justice, especially community justice, where life and other serious things hang in the balance, the situation or an event or an incident must be established by a multiplicity of witnesses, not just by one. In Canada we seem to have a single voice from the establishment media. How then are we to determine truth without a multiplicity of voices?On this episode of A Biblical Frame we have invited a few members of the Canadian media to join us to discuss how the Christian ought to engage the current media landscape. We are very thankful to our guests for their time. Subscribe so you do not miss any future episodes.

Our second episode, part 2 of our conversation with Dr. Aaron Kheriaty continues today. What have the churches learned from the pandemic?  What should they learn? As the covid narrative crumbles and examination of what went wrong begins, it is vital that we wrestle with such questions and that we prepare for whatever should be expected next.  We sat down with Aaron Kheriaty, author of The New Abnormal, and Douglas Farrow to discuss these things.  Psalm 139 - Re-Written for the Present DayBy Ivan De SilvaO State of the New World Order, you have hacked me    and know everything about meBy your all-encompassing surveillance, you know when I sit down or stand up.    by your implanted nanoparticles you know my thoughts even when I’m far away.By tracking my every central bank digital currency purchase you see me when I travel    and when I rest at home.    You know everything I do.Hear the rest in the podcastHosts:Ivan De Silva, MDiv, ThM, Instructor in Religious Studies, Trinity Western University, Pacific Life Bible CollegeJens Zimmermann, PhD, JI Packer Chair of Theology, Regent CollegeDouglas Farrow, Professor of Theology and Ethics, McGill UniversityAaron Kheriaty, MD, Fellow and Director of the Bioethics and American Democracy Program at the Ethics and Public Policy Center.

As we look back on the various stages of the Covid-19 pandemic it is plain to see that there are many ways the church responded to the virus and restrictions. Even today the frustration and division caused by Covid are still felt in our families, church communities, and society at large. Covid is apocalyptic because, true to the meaning of this word,  it “unveiled” the church’s weaknesses and lays bare her shortcomings. What have the churches learned from the pandemic?  What should they learn? As the covid narrative crumbles and examination of what went wrong begins, it is vital that we wrestle with such questions and that we prepare for whatever should be expected next.  We sat down with Aaron Kheriaty, author of The New Abnormal, and Douglas Farrow to discuss these things.   This will be the first of two episodes of this conversation discussing the covid apocalypse. In this first episode, the focus is on some of the themes of how the church responded to the virus and the restrictions.

In the second of our doublet of episodes with Dr. Charles Hoffe, we discuss the church’s response to the Covid crisis and what might the church need to do to pull herself out of the fog that her responses to the covid measures created. Join us in this conversational journey as we discuss and contemplate the nature and future of the church. Wherever we find the word of God purely preached and heard, and the sacraments administered according to the institution of Christ; there, it is not to be doubted, is a Church of God: for his promise can never deceive: “Where two or three are gathered together in my name, there am I in the midst of them.” - John CalvinThank you for listening.

We are back with a doublet of new episodes. It has been a while since a new episode was released but we have not given up on this ministry. We gathered together this past weekend and talked with Dr. Charles Hoffe, we recorded two episodes together and here is the first. “Unfortunately most of the medical profession has failed the moral integrity test because if you see evidence of harm you are not supposed to cover it up and there has been a massive cover up of the evidence of harm.” - Dr. Charles Hoffe In this episode we hear the story, research, and advice from Dr. Charles Hoffe, a British Columbia family doctor and emergency room doctor. Dr. Hoffe is currently under investigation by the provincial college because he started to ask questions and speak about vaccine injuries caused by the Covid-19 MRNA vaccines.

And this is the way to break out of the imaginary encirclement of our inertness, the easiest way for us and the most devastating for the lies. For when people renounce lies, lies simply cease to exist. Like parasites, they can only survive when attached to a person.We are not called upon to step out onto the square and shout out the truth, to say out loud what we think—this is scary, we are not ready. But let us at least refuse to say what we do not think!This is the way, then, the easiest and most accessible for us given our deep-seated organic cowardice, much easier than (it’s scary even to utter the words) civil disobedience à la Gandhi.Our way must be: Never knowingly support lies! Having understood where the lies begin (and many see this line differently)—step back from that gangrenous edge! Let us not glue back the flaking scales of the Ideology, not gather back its crumbling bones, nor patch together its decomposing garb, and we will be amazed how swiftly and helplessly the lies will fall away, and that which is destined to be naked will be exposed as such to the world.And thus, overcoming our temerity, let each man choose: Will he remain a witting servant of the lies (needless to say, not due to natural predisposition, but in order to provide a living for the family, to rear the children in the spirit of lies!), or has the time come for him to stand straight as an honest man, worthy of the respect of his children and contemporaries? - Aleksandr Solzhenitsyn, Live not by LiesPublished in November of 2021, or 621 days after the WHO declared the Covid-19 Pandemic, Till We Have Faces is Dr. Bruce Hindmarsh’s attempt at cataloguing and critiquing Covid policies in Canada. Dr. Steven Pelech wrote the foreword to this essay and it is because of that connection that we have invited him onto the show this week. Dr. Pelech is a leading researcher in Covid-19 immunity and we are grateful to sit with him and grill him with questions. We, like many of our listeners, are simply seeking the truth and we desire to listen and learn from experts. In this longer than normal episode, we wander through the details and intricacies of governmental covid restrictions, vaccines and vaccine effectiveness, and we seek advice for ourselves, the listeners, and the Church.

It is not an understatement to say that Bill C-4 could have severe effects on the witness of the Church in Canada. Due to the rushed nature of this legislation, pastors, priests, and Christian counsellors have been reeling since its adoption. Many are not sure what they can now say in a pastoring conversation.We hope to add some insight into this predicament. We are extremely grateful to have Dr. Iain Provan as a featured guest today. Dr. Provan has spent a significant portion of his last few years wading into this problem and speaking to countless church leaders about Bill C-4 and the impact on Christian ministry. We continue to create these episodes as a service to the church in Canada. If you are listening and enjoying the content, please leave a comment with requests for future episodes.

“What we have to do is look evil squarely in the eye and decide how we are going to resist it.” - Prof. Douglas FarrowIt may come as no surprise that when we gather together to record these episodes we enjoy some good food and drink and rich fellowship with one another. It was during one of our previous recording sessions that conversations around Prof. Douglas Farrow’s work on Chesterton and Dr. Stephen Dunning’s expertise with Lewis were being discussed. It turns out that both Lewis and Chesterton had some foresight into what we have experienced with COVID-19 and government mandates in the last two years. We are very excited to have two expert fellows on the show this week to discuss their prescient work. In this episode, Douglas Farrow and Stephen Dunning walk us through some of the writings of C.S. Lewis and G.K. Chesterton and lead us in a discussion of how their thoughts and words might offer some wisdom for us grappling with current events in Canada. “Lewis was also eerily prescient about what we have witnessed from governments during Covid, what I would describe as a form of scientific activism.  Think of all the calls to “follow the science,” as if science spoke univocally in support of whatever the current policy happened to be.  As an aside, this required everyone to consign yesterday’s policies to the memory hole and to ignore (or distort) what was happening in other jurisdictions, such as Florida or Sweden.  That Hideous Strength goes to macabre (and at times comic) lengths to demonstrate that the enemy of these scientific activists--these Controllers as Lewis calls them in The Abolition of Man, or directors of NICE in the novel--is clarity of thought, clarity of speech. The essential problem, according to Lewis in both these works, is as I suggested earlier, that the activists have rejected the only source of real authority through which they could justify the ends they seek to achieve.  And yet they are compelled to act, motivated by ends that they can only vaguely articulate.  And they most certainly do not want to look carefully at the concrete reality experienced by those who fall victim to the means they use to achieve these vague ends.” -Stephen Dunning, PhD, Professor Emeritus, Trinity Western UniversityHosts:Ivan DeSilva, MDiv, ThM, Instructor in Religious Studies, Trinity Western University, Pacific Life Bible CollegeJens Zimmermann, PhD, JI Packer Chair of Theology, Regent CollegeStephen Dunning, PhD, Professor Emeritus, Trinity Western UniversityDouglas Farrow, Professor of Theology and Ethics, McGill UniversityProducers:Curtis Meliefste, MDiv Student, ACTS SeminariesShow Links: This is a public episode.

Hello and welcome back to A Biblical Frame. With the busyness of the end of term crunch for many of us, our regular recording session was postponed. However, there is good news in store. Today we have our episode discussing technology and the church and next week we will release a special bonus episode discussing the prophetic words of C.S. Lewis and G.K. Chesterton. In this episode, we wanted to discuss the nature of technology and, to a degree, the relationship between technology and the church. Since March 2020 churches have rushed to digital forms of many historic Christian practices. Since the mandates for churches arrived so quickly and changed so often many pastors, priests, and church leaders did not have the capacity or time to think biblically about the nature of these changes. We hope that this podcast today does some of that work.“As I look at what Scripture says about technology, and as I look at the way it drives us to be discerning, I believe Scripture says this: technology, in and of itself, is neither good nor bad; it is a tool. But, to what end? If to God’s ends, it is good; if not, it is bad.” - Ed GerberHow can technology help the church? This podcast (and many others) are a testimony to the benefits of modern digital technology. But live-streamed worship and sacraments? Gatherings over zoom? Does that benefit Christ’s beloved bride? Lord willing, this podcast helps you think biblically about technology and the church.

Welcome to Episode 5 of A Biblical Frame. This week we welcome back Dr. Bruce Waltke and welcome Dr. Stephen Dunning to the show. We’re back on the topic of truth, what is it and how can we find it. In a world swirling with legacy or mainstream media and new alternative forms of media many people are left wondering how can they know what is true and what is not. How can we be wise about wading through the information fog surrounding current events today?“The connection between wisdom and truth is this: the wise person lives in truth, that is the wise person puts the parts of reality together into a meaningful whole that corresponds to the truth of reality.” - Jens ZimmermannWe’ve launched a YouTube channel where all the video versions of new episodes will be live.

Welcome to episode 4 of A Biblical Frame. Today we welcome Old Testament scholar Dr. Bruce Waltke and Professor of Economics at Simon Fraser University Douglas W. Allen to the show to discuss truth.It has been a common experience in the last number of years to disagree with one another on what we might hold as true. This is not unique to the past 2 years of our Covid lockdown world but the conversations surrounding Covid have shown the fissures surrounding truth in our relationships. In this episode, we explore how we might come to know and live by the truth. The media cycle whirls around us at astounding speeds and we are left wondering what is true and how should we live. “When you hear God’s word, do it. And don’t listen to somebody else if God really is clear to you; you are responsible before God for yourself. Be sure you are open to hear whatever it says, even if you don’t like it.” - Bruce WaltkeLinks:Covid Lockdown Cost/Benefits by Douglas W. AllenCovid Facts for Ordinary People by Douglas W.

Welcome to Episode 3 of A Biblical Frame. Today we take up the topic of resistance.It is shocking how much Canada (and the world) can change in the 3 weeks since our last episode and simultaneously stay the same.Trudeau has dealt with the “fringe minority” in Ottawa, Russia has invaded Ukraine, provinces and territories across Canada have begun to lift restrictions and yet the church is still being torn apart by restrictive covid policies. Pastors, priests, and parishioners everywhere are wondering if and when Christians ought to resist them. “So why do we resist? Well, we resist not only to push back the evil, and immediate harms that go with it, but we also resist the evil things sinful people do as a loving warning to them in order to win back sinners for God. Issuing warning to those who think they will be able to escape from the inescapable God is a form of love. This is why the prophets thunder with words and actions of resistance; because to resist in this way is a form of love.” - Ed GerberIn this episode we welcome back Douglas Farrow and host Michael Rectenwald as a special guest. You will hear some prepared thoughts from each host as well as free-flowing conversation.

Welcome to Episode 2 of A Biblical Frame. In light of the worldwide wide ‘trucker’ protests and convoys that are calling out for freedom, we felt it pertinent to discuss freedom from a biblical and theological perspective. We are very thankful to have Douglas Farrow, Professor of Theology and Ethics at McGill University in Montreal join for this discussion. “We may think that when following pandemic rules we love our neighbour and we preserve, at least, the freedom of gathering for worship. In effect, however, we have already given up freedom because our choice is no longer linked to truth. Are we surprised that division and hatred have seeped into our churches over the mandates? Calling compliance an act of love that is bereft of truth leads to division. True Christian discipleship requires us to hold together freedom, love, and truth and only when we do that can we follow Christ freely and responsibly.” - Jens ZimmermannPlease leave a comment below if you have a question and share this with anyone who you think will benefit. Later this week we will send another update with the full video of the podcast. In light of the news coming from Ottawa this morning we wanted to get this podcast out as soon as possible.

Welcome to A Biblical Frame. This is a spontaneous project that arose from a group of pastors and theologians who recognized the great need for theological direction for Christ’s church in Canada. Canada has faced totalitarian restrictions in response to the Covid-19 pandemic. While there may have been a time to acquiesce to the provincial health officers, that time is coming to an end and the church needs help. In this first episode, (bios below) Ed, Hans, Jens, and Ivan discuss fear. What ought the Christian really be afraid of? Should we fear covid? Thank you for listening. Our hope and prayer is that these episodes, however sporadic they come, benefit you and benefit the bride of Christ.
