I can't be subject to the both of them.
Under which pope did you decide to apostatize?
1 John 2:
19 They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us.
20 But ye have an unction from the Holy One, and ye know all things.
21 I have not written unto you because ye know not the truth, but because ye know it, and that no lie is of the truth.
22 Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son.
23 Whosoever denieth the Son, the same hath not the Father: he that acknowledgeth the Son hath the Father also.
Apostasy defined by the Apostle John is denying the Father and the Son. I do believe you owe boatbums a huge apology.
"Now, therefore, we declare, say, determine and pronounce that for every human creature it is necessary for salvation to be subject to the authority of the Roman pontiff" (Porro subesse Romano Pontifici omni humanae creaturae declaramus, dicimus, definimus, et pronuntiamus omnino esse de necessitate salutis). (http://www.newadvent.org/cathen/15126a.htm)
It sounds like an ex cathedra pronouncement. Has it ever been revoked?
Which Pope are you subject to? Pope St Pius X is dead.
