From the Word
19 Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 teaching them to observe all that I have commanded you; and lo, I am with you always, to the close of the age.”
Matthew 28:19–20, RSV
We have in the holy Scriptures and in the Creed sufficient information concerning the Holy Trinity, and all that is necessary for the instruction of ordinary Christians. That the simple Christian may recognize that there is but one divine essence and one God, who is tri-personal, a special work, peculiar to himself, is ascribed to each person. To the Father we ascribe the work of creation; to the Son the work of redemption; to the Holy Spirit the power to forgive sins, to gladden, to strengthen, to transport from death to life eternal.
The thought is not that the Father alone is Creator, the Son alone Redeemer, and the Holy Ghost alone Sanctifier. The creation and preservation of the universe, atonement for sin and its forgiveness, resurrection from the dead, and the gift of eternal life — all these are operations of the one Divine Majesty as such. Yet the Father is especially emphasized in the work of creation, which proceeds originally from him as the first person; the Son is emphasized in the redemption he has accomplished in his own person; and the Holy Spirit in the special work of sanctification, which is both his mission and revelation. Such distinction is made for the purpose of affording Christians the unqualified assurance that there is but one God and yet three persons in one divine essence — truths which the sainted fathers have faithfully gathered from the writings of Moses, the prophets, and the apostles, and which they have maintained against all heretics.
This faith has descended to us by inheritance, and by his power God has maintained it in the Church, against sects and adversaries, unto the present time. So we must abide by it in its simplicity and not attempt to be wise. Such articles of faith appear utterly foolish to reason. Paul aptly calls the gospel foolish preaching wherewith God saves such souls as do not depend on their own wisdom, but simply believe in the Word. Those who will follow reason in the things dealt with in these articles, and will reject the Word, shall be defeated and destroyed in their wisdom.
