In answer to the objection that the doxology in the form “with the Spirit” has no written authority, we maintain that if there is no other instance of that which is unwritten, then this must not be received. But if the greater number of our mysteries are admitted into our constitution without written authority, then, in company with the many others, let us receive this one. For I hold it apostolic to abide also by the unwritten traditions. “I praise you,” it is said, “that you remember me in all things and keep the ordinances as I delivered them to you,” and “Hold fast the traditions which you have been taught whether by word or by our epistle.”
To which course many nations of those barbarians who believe in Christ do assent, having salvation written in their hearts by the Spirit, without paper or ink, and, carefully preserving the ancient tradition,
Hence it is manifest, that they did not deliver all things by Epistle, but many things also unwritten, and in like manner both the one and the other are worthy of credit. Therefore let us think the tradition of the Church also worthy of credit. It is a tradition, seek no farther. Here he shows that there were many who were shaken.
Paul did not instruct Timothy in his duty through letters alone, but also through the spoken word. He shows this, both in many other passages, as where he says, “whether by word or our epistle,” and especially here. Let us not, therefore, suppose that Paul spoke anything imperfectly that was related to doctrine. For he delivered many things to Timothy without writing. He reminds him of these when he says, “Hold fast the form of sound words, which you have heard from me.” After the manner of artists, I have impressed on you the image of virtue, fixing in your soul a sort of rule, model and outline of all things pleasing to God. Therefore, cling to these things, and whether you are meditating on any matter of faith or love, or of a sound mind, form your ideas from what I have taught you. It will not be necessary to consult others for examples, when all has been deposited within yourself.
Therefore, brethren, stand fast and hold the tradition of the apostles and the apostolic seat, "that our Lord Jesus Christ and our Father, which hath loved us, and hath given us everlasting consolation and good hope through grace, may comfort your hearts, and stablish you in every good work and word."
Sy; nor is there any other cause whence they find themselves compelled to deny the Paraclete more than the fact that they esteem Him to be the institutor of a novel discipline, and a discipline which they find most harsh: so that this is already the first ground on which we must join issue in a general handling (of the subject), whether there is room for maintaining that the Paraclete has taught any such thing as can either be charged with novelty, in opposition to catholic tradition.
So truly did he turn away from his early opinions: nor did he sin by becoming an emulator not of ancestral but of Christian traditions,
and who has given us an everlasting consolation
For He is their Fater, He consoles them, and they cannot be his sons without consolation. And because there is consolation in prosperous lands, Paul adds "eternal" so that he might separate earthly consolation from that which is in eternal things.
and good hope in grace
Becase there is hope in prperous times, he added "good" so that he might separate earthly hope from that which is in heavenly things.
