The Apostle Paul, following the example of Jesus Christ and all the other holy apostles, commands converted Jews, Israelites and Gentiles to commemorate the Passover and celebrate the Feast of Unleavened Bread (since they were never "done away" as Satan lies, but magnified in their meaning):
"For even Christ our PASSOVER is sacrificed for us: Therefore let us keep the FEAST...with unleavened bread of sincerity and truth" (1 Cor. 7-8).
