4. The Lord Jesus Christ is the Head of the church, in whom, by the appointment of the Father all power for the calling, institution, order, or government of the church, is invested in a supreme and sovereign manner;g neither can the Pope of Rome in any sense be head thereof, but is that antichrist, that man of sin, and son of perdition, that exalteth himself in the church against Christ, and all that is called God; whom the Lord shall destroy with the brightness of His coming.h
(g) Col 1:18; Matt 28:18-20; Eph 4:11-12
(h) 2 Thess 2:2-9

I would add that any man (or woman) that exalts himself in this manner is anti-Christ, including non-Papists, and Southern Baptists.
