Catechism Question #24 (May)
Q. How does Christ execute the office of a priest?
A. Christ executes the office of a priest, in His once offering up Himself a sacrifice to satisfy divine justice, and to reconcile us to God, and in making continual intercession for us.
Hebrews 2:17 - Therefore, in all things He had to be made like His brethren, that He might be a merciful and faithful High Priest in things pertaining to God, to make propitiation for the sins of the people.
