My response to any problem we have in the Catholic Church is the following;
from the Gospel of Matthew, Chapter 16;
13 When Jesus went into the region of Caesarea Philippi he asked his disciples, "Who do people say that the Son of Man is?" 14 They replied, "Some say John the Baptist, 10 others Elijah, still others Jeremiah or one of the prophets." 15 He said to them, "But who do you say that I am?" 16 Simon Peter said in reply, "You are the Messiah, the Son of the living God." 17 Jesus said to him in reply, "Blessed are you, Simon son of Jonah. For flesh and blood has not revealed this to you, but my heavenly Father. 18 And so I say to you, you are Peter, and upon this rock I will build my church, and the gates of the netherworld shall not prevail against it. 19 I will give you the keys to the kingdom of heaven. 14 Whatever you bind on earth shall be bound in heaven; and whatever you loose on earth shall be loosed in heaven."

And over thirty times in our history Anti Popes existed and nothing any one of them said binded a single catholic.
Our Lord also Taught thus: MATTHEW 7
9 *Or what man is there among you, of whom if his son shall ask bread, will he reach him a stone?
10 Or if he shall ask a fish, will he reach him a serpent?
11 If you then being evil, know how to give good gifts to your children: how much more will your Father, who is in heaven, give good things to them that ask him?
12 *All things, therefore, whatsoever you would that men should do to you, do you also to them. For this is the law and the prophets.
13 *Enter ye in at the narrow gate: for wide is the gate, and broad is the way that leadeth to destruction, and many there are who enter by it.
14 How narrow is the gate, and strait is the way, which leadeth to life: and few there are who find it!
15 Beware of false prophets, who come to you in the clothing of sheep, but inwardly they are ravenous wolves.
16 By their fruits you shall know them. Do men gather grapes off thorns, or figs off thistles?
17 Even so every good tree bringeth forth good fruit, and the bad tree bringeth forth bad fruit.
18 A good tree cannot yield bad fruit, neither can an bad tree yield good fruit.
19 *Every tree that yieldeth not forth good fruit, shall be cut down, and shall be cast into the fire.
20 Wherefore by their fruits you shall know them.
So ask yourselves what are the fruits?
