2018-12-16. The Altar is (1) a symbol of Christ, (2) a table for a meal, and (3) an altar for sacrifice. We bow and the priest kisses the altar because it's a symbol of Christ. It's a table just like Jesus had at the Last Supper when He instituted the Eucharist. It's an altar for sacrifice where we place our whole selves to offer to God in union with Jesus' sacrifice to the Father.
