You don't leave the Bride-- you abase yourself to Heaven and implore God to rescue Her.
The body of Christ is something a person is, not something a person joins and can leave.
And Roman Catholicism is no bride of Christ.
To equate the corruption and immorality that infests Catholicism with the purity and sinlessness of Christ is reprehensible.
If Catholicism wishes to take on itself the name of the Bride of Christ, it needs to start acting like it and at this point, as has been the case for well over 1,000 years based on evidence from within Catholicism itself, it doesn't and it hasn't.
Get back to me when the Catholic hierarchy cleans house and lives in humble, repentant obedience to the Scripture it claims to have written.
They can start here......
1 Corinthians 5:1-13 It is actually reported that there is sexual immorality among you, and of a kind that is not tolerated even among pagans, for a man has his father's wife. And you are arrogant! Ought you not rather to mourn? Let him who has done this be removed from among you.
For though absent in body, I am present in spirit; and as if present, I have already pronounced judgment on the one who did such a thing. When you are assembled in the name of the Lord Jesus and my spirit is present, with the power of our Lord Jesus, you are to deliver this man to Satan for the destruction of the flesh, so that his spirit may be saved in the day of the Lord.
Your boasting is not good. Do you not know that a little leaven leavens the whole lump? Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed. Let us therefore celebrate the festival, not with the old leaven, the leaven of malice and evil, but with the unleavened bread of sincerity and truth.
I wrote to you in my letter not to associate with sexually immoral people—not at all meaning the sexually immoral of this world, or the greedy and swindlers, or idolaters, since then you would need to go out of the world. But now I am writing to you not to associate with anyone who bears the name of brother if he is guilty of sexual immorality or greed, or is an idolater, reviler, drunkard, or swindler—not even to eat with such a one. For what have I to do with judging outsiders? Is it not those inside the church whom you are to judge? God judges those outside. “Purge the evil person from among you.”
This business of asking God to*rescue* Catholicism is meaningless. They need to take action. They know what to do. God has already revealed it to them. They are now responsible to act on it instead of begging God to do for them what they won't do in simple obedience.If they are not going to obey, then why should God be expected to deliver them?
