Sadly, you are right. There are very few trustworthy, righteous men in the hierarchy. I can't believe I am actually saying that.
I guess this stuff is not new, only the reasons change.
When the Council of Nicaea was called in 325, even though he was only still only a deacon, his Bishop chose Athanasius to accompany him as a periti. There he amazed and impressed the Council Fathers with his thorough knowledge of the Faith and his masterful apologetics approach of defending the Faith, especially against the Arian heresy. Though Arianism was soundly condemned at Nicaea, it did not go away. Rather it spread further and, were it not for men like Athanasius, who knows what further damage might have been done. It was Athanasius himself who illustrated the great damage done when he said, "The floor of hell is paved with the skulls of bishops." He was, of course, referring to those bishops - the vast majority - who had been lured away from the True Church in following the false teachings of Arius. If that many bishops were in hell, how many who followed them down the wide path to perdition also were? They say for every priest who loses his soul, 1000 souls are lost; for every bishop who loses his eternal soul, 10,000 souls are denied the Heavenly portals.
This time, don't let any of them get away. Unitarians have done a lot of good but, considering where they are now, it would have been better had none escaped in the 4th century.
There is always hope and always forgiveness. And isn't the saying something like this:
"With prayer, all things are possible."?
