Welcome to Certainty for Eternity, the podcast where we explore Catholicism and Christianity from a Protestant perspective.

In this episode, Mark and Rayne celebrate the 1700th anniversary of the Council of Nicaea (325 AD), where the Nicene Creed was written. Together they unpack:

• Why the Nicene Creed matters for both Protestants and Catholics

• How words like one, holy, catholic, apostolic are understood differently

• What the Pope has said about unity and why Protestants respond differently

• The historical challenges of Gnosticism, Arius, and the early church

• Practical ways to invite, share, show Jesus, and lovingly engage Catholic friends today

If you’ve ever wondered what Catholics and Protestants mean when they recite the same words but hold different worldviews, this episode will equip you for better conversations, deeper faith, and Christ-centred unity.
