1 Coríntios 5:8

The feast of Unleavened Bread began the day after Passover. The Jews regarded both Passover and the feast of Unleavened Bread as one festival (cf. Exodus 23:15; Exodus 34:18; Deuteronomy 16:6). As believers whose Pascal Lamb had died, it was necessary that the Corinthians keep celebrating the feast and worshipping God free of leaven that symbolically represented sin. The old leaven probably refers to the sins that marked the Corinthians before their conversion. Malice and wickedness probably stand for all sins of motive and action. Sincerity and truth are the proper motive and action with which we should worship God. This verse constitutes a summary exhortation.
