III. +The Gospel which Paul preached was not human+--he did not receive it, neither was he taught it by man; and preached it not by human but by Divine authority. 1. Christ is the great prophet and doctor of the Church. His office is: (1) To manifest and reveal the will of the Father touching the redemption of mankind. (2) To institute the ministry of the Word and to call and send ministers. (3) To teach the heart within by illuminating the mind and by working a faith of the doctrine taught. 2. There are two ways whereby Christ teaches those who are to be teachers. (1) By immediate revelation. (2) By ordinary instruction in schools by the means and ministry of men. IV. +They who are to be teachers must first be taught,+ and they must teach that which they have first learned themselves. They are first to be taught, and that by men where revelation is wanting. This is the foundation of the schools of the prophets. All men should pray that God would prosper and bless all schools of learning where this kind of teaching is in use.--_Perkins._ _The Gospel a Divine Revelation._ +I. It is not constructed by human ingenuity.+--"The gospel which was preached of me is not after man" (ver. 11). +II. It derives no authority from man.+--"For I neither received it of man" (ver. 12). +III. It is not acquired by mere mental culture.+--"Neither was I taught it." +IV. It is a direct and special revelation from heaven.+--"But by the revelation of Jesus Christ." _Apostolic Assurance of the Supernatural Character of the Gospel._--1. It is the custom of the adversaries of the truth, when they have nothing to say in reason against the doctrine itself, to cast reproach on those who preach it, and to question their call and authority to preach, that so they may indirectly at least reflect upon the doctrine. 2. As none may take upon him to dispense the Word of God publicly unto others without a call from God, so there are several sorts of callings: one of men and ordinary when God calls by the voices and consent of men; another of God and extraordinary, the call of the Church not intervening. 3. It is required of an apostle to have the infallible knowledge of the truth of the Gospel and this not wholly by the help of human means, as we learn at schools and by private study, but mainly by immediate inspiration from the Spirit of God. Paul shows that the Gospel was not taught him of man; and this he saith, not to depress human learning, but that he may obviate the calumny of his adversaries who alleged he had the knowledge of the Gospel by ordinary instruction from men only, and so was no apostle.--_Ferguson._ _MAIN HOMILETICS OF THE PARAGRAPH.--Verses_ 13, 14. _A Zealous Ritualist--_
