In the Communion of the Apostles, we visually encounter the catechesis presented in the Catechism on the Paschal Banquet, “The altar, around which the Church is gathered in the celebration of the Eucharist, represents the two aspects of the same mystery: the altar of sacrifice and the table of the Lord. (CCC 1383). Therefore in this image, standing in priestly vestments, we encounter Christ as both the Priest offering the sacrifice and as the unblemished Lamb being sacrificed.
