What two mysteries does Paul talk about before 1 Corinthians 15?
Paul first addresses the mystery of the Gentiles becoming one with God. Then he addresses the mystery of God's identity as the triune God—Father, Son, and Holy Spirit. These two mysteries come before his discussion of the mystery in 1 Corinthians 15.
Les explains that before 1 Corinthians 15, Paul dealt with two distinct mysteries. The first is the Gentiles becoming one with God. The second is the revelation of who God really is as the triune God—Father, Son, and Holy Spirit. Earlier, the mystery of God the Father and of Christ was mentioned, in whom are hid all the treasures of wisdom and knowledge. The Old Testament was vague about the Trinity, but Paul brings out this revelation. Then, in 1 Corinthians 15, Paul turns to a different mystery.
