By Msgr. Charles Pope - The clearest example of this is Passover. Christ Jesus is our Passover (or paschal) Lamb and every Easter we solemnly celebrate that Christ our Passover Lamb has been sacrificed, once and for all. We are delivered from death and make our Exodus from the slavery of sin to the glorious freedom of the children of God... So, we do more than celebrate Passover, in Christ we fulfill it. That is, we partake fully of all that the Passover pointed to. In a certain sense we celebrate it every Sunday, which is a mini-Pasch (or Easter).
