Tertullian
Patristic
c. A.D. 150–220
“What is this deposit? Is it so secret as to be supposed to characterize a new doctrine? or is it a part of that charge of which he says, "This charge I commit unto thee, son Timothy? " and also of that precept of which he says, "I charge thee in the sight of God, who quickeneth all things, and before Jesus Christ who witnessed a good confession under Pontius Pilate, that thou keep this commandment? " Now, what is (this) commandment and what is (this) charge? From the preceding and the succeeding contexts, it will be manifest that there is no mysterious hint darkly suggested in this expression about (some) far-fetched doctrine, but that a warning is rather given against receiving any other (doctrine) than that which Timothy had heard from himself, as I take it publicly: "Before many witnesses" is his phrase.”
