24. The Lord is called the Son of Humanity when the subject is his suffering. This we can tell from the following passages.
Jesus said to his disciples, “Behold, we are going up to Jerusalem, and the Son of Humanity will be betrayed to the chief priests and to the scribes; and they will condemn him to death and hand him over to the Gentiles, and they will whip him, and spit on him, and kill him. On the third day, though, he will rise again.” (Mark 10:33-34)
Likewise elsewhere, where it foretells his suffering, as in Matthew 20:18-19; Mark 8:31; Luke 9:22:
Jesus said to his disciples, “Behold, the hour is at hand, and the Son of Humanity is being betrayed into the hands of sinners.” (Matthew 26:45)
The angel said to the women who came to the tomb, “Remember what he said to you: ‘The Son of Humanity must be betrayed into the hands of sinful people and be crucified and rise again on the third day.’” (Luke 24:6-7)
The reason the Lord then called himself the Son of Humanity is that he allowed people to treat him the way they were treating the Word, as has already been explained more than once [, ].
