I know chestnutmare brought up 1 Cor 7:14.

Pilgrim, I am interested in how you interpret this verse and what is meant by "holy."

I know Francis Turretin and John Gill believe the holiness to be a external or federal holiness. Turretin says they are called holy because they are born into christianity and not heathenism which is a sate of "uncleanness."

Before I entered this thread I interpreted this verse differently, but now I think I agree with Turretin and Gill. But where else does holiness refer to christianity?
