Again we refer to the apostle Paul letter to the Corinthians (1 Corinthians 5:8). We are instructed to keep the feast, but not with the old unleavened practices, that of removing all leaving agents, and whatever was leavened from our homes. We keep the feast in the understanding of what the old customs pointed to, that being the removal of sin from our lives. For leaven is merely a symbol, it has no power of itself. The Feast of Unleavened Bread has a seven day observance period. The first day and the seventh day are annual Sabbaths on which holy convocations (gatherings) are to be held. In loving obedience to God we assemble on those Holy days in recognition of the work our Lord has begun in us and has promised to finish (Philippians 1:6).
The fifteenth of the month of Abib is to be observed as the first day unleavened bread. It symbolizes the beginning of God work of removing sin from our lives. This began the moment we received and partook of the sacrifice, Christ Jesus our Passover. The twenty first day of Abib, the last day of the seven day observance is observed to commemorate Christ finishing His work in us. Again it is our prayer that the God and Father of our Lord and Savior Christ Jesus will bless you to understand the observance of the Feast of Unleavened Bread.
