1 Corinthians: The theme of the letter is the need for unity in the Church, which is the Mystical Body of Christ, and charity. He deals with divisions in the Church and the orderly use of charismatic gifts such as speaking in tongues. Towards the end he describes the resurrection of the dead and says belief in the resurrection is a fundamental part of the Christian faith.
