Believe and confess what is believed. Why then the need to suffer? Man is a being that tends to gather all his knowledge and to reduce it to a systematic knowledge; by nature he is very given to boasting because of what he knows; so that a knowledge that God gives him does not fall in the “library” of his knowledge, and the Revelation is lost, it is necessary for man to process his knowledge through “experiences” that lead him to put aside his tendency to boast because of what he knows, and to put it aside; in the process, man discovers God speaking to his spirit.
It was necessary for the Christ to suffer because only in this way man could understand the way of the Revelation of salvation, He led the way.
