Israelitism, and the letter of Jesus' doctrine without the spirit.
3. This heterogeneous mass became acceptable because it was sanctioned by kings and enforced as the church of the state. As it had a little from all the religions, it offered balm to the forced worshipers from each sect, and thus quickly became popular. It is not the doctrine of Jesus Christ, however, and never has been, in any of its many forms and sects. Here and there a gleam of Truth has come to spiritually awakened devotees, and they have broken away from the institution and formed newer and higher standards of Truth; but all have been far short of the original doctrine set forth by Jesus and His disciples.
4. Jesus never organized a church on earth, nor did He authorize anyone else to do so. He said to Peter, "Upon this rock I will build my church." He did not tell Peter that He was to be the head of the church, with a line of popes to follow. He said, "I will build my church" (ecclesia, assembly, or called-out ones). Jesus Christ is still the head of His "assembly," and its only organization is in Spirit. Whoever attempts to organize it on earth, with creeds, tenets, or textbooks of any kind or description as authority, is in direct opposition to His word and His example. He gave but one guide, one source from which His followers should receive their inspiration: "The Holy Spirit, whom the Father will send in my name, he shall teach you all things, and bring to your remembrance all that I said unto you."
