How Theology Works

How do we know what God has revealed?

5 lessons

Before studying any particular teaching, you need to know where Catholic teaching comes from and how to tell a defined dogma from settled teaching and from a theologian’s opinion. This unit sets out the ground rules. Every later lesson is labelled with the categories you learn here, so this unit comes first.

Philosophy you will need

Knowledge by testimony (why believing a reliable witness is reasonable) and the limits of what reason alone can reach.

Watch out for

Infallibility does not mean the Pope is sinless or that everything he says is infallible. Development of doctrine is not the Church changing its mind.
