When, exactly, did the Holy Spirit begin His long vacation? When, exactly, did Christ's promises to "be with you always, until the end of the age" and to lead His Church "to all truth" turn out to have been fraudulent?
If you believe error means the Holy Spirit took a vacation, I can only commend the first 4 chapters of Revelation to you for further study. In it you will find an Apostle detailing his direct inspired message from the glorified Christ that error was in some Churches.
If you believe this error means Christ didnt' keep his promises to "be with you always, until the end of the age", I can only say the Scriptures disagree. He was with Israel, keeping His covenants, even during their darkest hours, when He said, "And what was God's answer to him? "I have reserved for myself seven thousand who have not bowed the knee to Baal."
Christ remained with His Assembly even during the dark hours throughout the ages, while most in His Church slipped into syncretic paganism. He was there to give it a rebirth during the Reformation years. He is there today, wherever believers are found.
That no more refers to one organic church and precludes any error than do the many promises of Divine presence, guidance and preservation given to the OT people of God, (Gn. 12:2,3; 17:4,7,8; Ex. 19:5; Lv. 10:11; Dt. 4:31; 17:8-13; Ps, 11:4,9; Is. 41:10, Ps. 89:33,34; Jer. 7:23) "Who are Israelites; to whom pertaineth the adoption, and the glory, and the covenants, and the giving of the law, and the service of God, and the promises; Whose are the fathers, and of whom as concerning the flesh Christ came, who is over all, God blessed for ever. Amen. (Romans 9:4-5)
Nor do we know all the truth that there is to know, or can claim comprehensive doctrinal unity, but the Spirit will be guiding the body of Christ into all Truth, though here we yet see thru a glass, darkly.
