There is no secular.

We often use the word 'secular' to denote something that is separate and discrete from the church - that is the sacred. It's a useful shorthand to talk about the differences and tensions between what the apostle John called 'the world' and the in-breaking Kingdom of God.

In a real sense however, there is no such thing as secular. God has created everything, and is in-process of redeeming everything, reconciling everything to Himself, including all people - if they will but turn and be reconciled. So, I will use the word secular with some care - realising that the whole Universe belongs to God, and all that is in it.
