> while Jesus Christ never gave to abortion the slightest mention
In his defense, Jesus came to fulfill the old law and not abolish it, as directly stated by himself. The old law has the 5th commandment, "Thou shalt not kill," which in the times of Jesus was unanimously interpreted to cover abortion (Psalm 139 being one reason why) and Jesus, by not speaking against this interpretation (unlike other interpretations), left that view unchanged.
