MADists think there was only one mystery hidden since the foundation of the world.
If we count the mysteries hidden since the foundation of the world in the NT, there are 10 of them.
Paul reveals 8 of them, and John 2 of them.
As I stated earlier, Christ Jesus spoke of many of the mysteries hidden since the foundation of the world through parables.
MADists get confused over Rom 16:25-26. They think the "Revelation of the mystery" that Paul speaks of in Rom 16:25 was given to Paul, and only Paul.
That's not true. Christ Jesus was the first to speak of the mysteries hidden since the foundation of the world, and Paul makes it clear that these mysteries were given to the Apostles.
