S. Matthew 28:16-20

But the eleven disciples went into Galilee, unto the mountain where Jesus had appointed them. And when they saw him, they worshipped him: but some doubted. And Jesus came to them and spake unto them, saying, All authority hath been given unto me in heaven and on earth. Go ye therefore, and make disciples of all the nations, baptizing them into the name of the Father and of the Son and of the Holy Ghost: teaching them to observe all things whatsoever I commanded you: and lo, I am with you alway, even unto the end of the world.
