We have now to consider Christ's doctrine, about which there are four points of inquiry:

A[1] Whether Christ should have preached to the Jews only, or to the Gentiles also?

A[2] Whether in preaching He should have avoided the opposition of the Jews?

A[3] Whether He should have preached in an open or in a hidden manner?

A[4] Whether He should have preached by word only, or also by writing?

Concerning the time when He began to teach, we have spoken above when treating of His baptism (Q [29], A [3]).
