Ephesians

(Eph 1:1 [NET])
From Paul, an apostle of Christ Jesus by the will of God, to the saints [in Ephesus], the faithful in Christ Jesus.

Breaking it down:

The letter is from Paul

He is an apostles of Jesus Christ

He is an apostle by the will of God. No doubt a reference to his salvation experience on the road to Damascus. There's no doubt that Paul has a very high view of God's sovereingnty, especially as it relates to salvation.

The letter MIGHT be to the Ephesians, or it might not, being intended as an enclyclical letter to ALL the Churches.

Either way, that's what it turned into. As did ALL the letters Paul wrote. It was their acceptance of these that led to their inclusion in the Canon.

Anyway, the letter is to the SAINTS, which is a crucial point in understanding the themes of the letter. Who are the saints?

The faithful in Christ Jesus.

Not those who simply say they believe, but the ones who live like it.
