Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.

Jerome
AD 420
All who abuse to other purposes the money of the Temple, and the contributions for the use of the Church, purchasing with them their own pleasure, are like the Scribes and Priests who bought this lie, and the blood of the Saviour. For when coming to His Passion the Lord had said to His disciples, “After I am risen I will go before you into Galilee;” and the Angel said the same to the women. Therefore the disciples obey the command of their Master. Eleven only go, for one had already perished.
After His Resurrection, Jesus is seen and worshipped in the mountain in Galilee; though some doubt, their doubting confirms our faith.
Power is given to Him, Who but a little before was crucified, Who was buried, but Who afterwards rose again.
They first then teach all nations, and when taught dip them in water. For it may not be that the body receive the sacrament of Baptism, unless the soul first receive the truth of the Faith. “In the name of the Father, the Son, and the Holy Spirit,” that they whose Godhead is one should be conferred at once, to name this Trinity, being to name One God.
Didymi Lib. ii, de Spir. Sanct.: And though some one there may be of so aversea spirit as to undertake to baptize in such sort as to omit one of these names, therein contradicting Christ Who ordained this for a law, his baptism will effect nothing; those who are baptized by him will not be at all delivered from their sins. From these words we gather how undivided is the substance of the Trinity, that the Father is verily the Father of the Son, and the Son verily the Son of the Father, and the Holy Spirit the Spirit of both the Father and the Son, and also the Spirit of wisdom and of truth, that is, of the Son of God. This then is the salvation of them that believe, and in this Trinity is wrought the perfect communication of ecclesiastical discipline. The Son is the Offspring of the Unbegotten, One of the One, True of the True, Living of the Living, Perfect of the Perfect, Strength of Strength, Wisdom of Wisdom, Glory of Glory; the Image of the Unseen God, the Form of the Unbegotten Father. Neither can the Holy Spirit be separated from the confession of the Father and the Son. And this consolation of our longing desires is absent from no place. He is the pledge of our hope in the effects of His gifts, He is the light of our minds, He shines in our souls. These things as the heretics cannot change, they introduce into them their human explanations. As Sabellius who identifies the Father with the Son, thinking the distinction to be made rather in name than in person, and setting forth one and the same Person as both Father and Son. As Ebion, who deriving the beginning of His existence from Mary, makes Himnot Man of God, but God of man. As the Arians, who derive the form, the power, and the wisdom of God out of nothing, and in time. What wonder then that men should have diverse opinions about the Holy Spirit, who thus rashly after their own pleasure create and change the Son, by whom that Spirit is bestowed?.
Observe the order of these injunctions. He bids the Apostles first to teach all nations, then to wash them with the sacrament of faith, and after faith and baptism then to teach them what things they ought to observe; “Teaching them to observe all things whatsoever I have commanded you.”.
He then who promises that He will be with His disciples to the end of the world, shows both that they shall live for ever, and that He will never depart from those that believe.
