Christ gave his command to his disciples to go out and baptize all people: "Full authority has been given to me both in heaven and on earth; go therefore, and make disciples of all nations. Baptize them in the name of the Father, and of the Son, and of the Holy Spirit. Teach them to carry out everything I have commanded you. And know that I am with you always, until the end of the world!" (Mt. 28:18-20)
Through Baptism we are formed in the likeness of Christ: "It was in one Spirit that all of us, whether Jew or Greek, slave or free, were baptized into one body." (1 Cor. 12:13) We become sharers in the sacramental bond of unity which links all who have been reborn by means of it. But baptism is only a beginning, and not an end. It is an initiation into a way of life which directs us toward the acquiring of fullness of life in Christ.
Baptism is the sacrament by which we enter into the faith of the Church. Through Baptism we are welcomed into God's family - the Church - and are called to share everlasting life with him. The Sacrament of Baptism is the first of three sacraments called the Sacraments of Initiation. It is the prerequisite for receiving the other sacraments. Baptism finds its fulfillment in the reception of Holy Communion and Confirmation.
