Well let me see Judas was picked for the part he had in the plan of salvation. The original 12 were before Pentecost and my how Peter changed after Pentecost. Jesus would never have selected child rapists to be leaders, He would not select popes who had orgies, who the one who dug up the dead. None of those activities are part of the salvation plan and is after Pentecost.
Scripture tells us to use discernment. It tells us the fruit of the spirit and fruit of the world. Your institution wallows in the fruit of the world. If it is Jesus' bride it must meet certain standards and it doesn't. We are told to flee from false teachers your institution has false doctrines because it has strayed so far away from the Word of God.
Arch that is such a poor excuse for evil fruit, to bring up the 12. They would not have tolerated the sexual sin of leaders that your church has hidden, lied about. Jesus said sin will be exposed. Your institution's sin has been exposed throughout the centuries and shows it is not what it claims to be.
Luke 12:2
But there is nothing covered up that will not be revealed, and hidden that will not be known.
Galations 5
17 for the flesh desires what is contrary to the Spirit, and the Spirit what is contrary to the flesh. They are in conflict with each other, so that you are not to do whatever you want. 18 But if you are led by the Spirit, you are not under the law.
19 The acts of the flesh are obvious: sexual immorality, impurity and debauchery; 20 idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions 21 and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.
Your institution has the acts of the flesh, its leaders have been involved in:
sexual immorality, impurity and debaucher, idolatry, hatred, discord, jealousy, selfish ambition, envy, fits of rage, fractions, orgies throughout the centuries.
