From where/whom do they trace their descent? Do they attempt to leapfrog back to the time of Christ? And do they state doctrine without resorting to Reformation terminology? How do they do this?

[P-Marlowe]

From where/whom do they trace their descent?

I think the simplest way to express the idea is that God does not have grandchildren.

And do they state doctrine without resorting to Reformation terminology?

Some do, some don't.

How do they do this?

By the Grace of God and by the authority of scripture and by the leading of the Holy Spirit.
