Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.The Sacrament of Baptism is often called "The door of the Church," because it is the first of the seven Sacraments not only in time, but also in priority. The reception of all other Sacraments depends on it. Baptism is the first of the three Sacraments of Initiation, the other two being the Sacrament of Confirmation and the Sacrament of Holy Communion. Once baptized, a person becomes a member of the Church.- Acts 2:38
