Ephesians 3:2-5

I have once formerly written on this subject, and you have heard of it. I have explained the grace which God imparted peculiarly to me for your benefit, and the revelation made known to me about you. You have but to read what I then wrote to perceive my initiation into and my understanding of this infinite mystery of the Christ, not known to previous generations of men, but in this age spiritually revealed to his holy apostles and prophets.
