Yes. That would be the one!
You show signs of Donatism, a heresy condemned all the way back in 325 at the Council of Nicea. To wit: if a member of the Church isn’t “sinless,” then he is not a member. You seem to expect the same sinlessness that Donatus and his followers erroneously demanded.
But the Church is comprised of sinners and, indeed, exists as a means of cleansing them from their sins. Consider that, in Matthew 13:24-30, the Church is clearly shown by Christ Himself to be comprised of both the “wheat” and the “tares.” Do not take scandal because individual members are sometimes not sufficiently holy for your liking. Remember, it is as sinful to take scandal as it is to give scandal (Matthew 18:5-7).
Unfortunately, the institution itself has become the Devil’s tool, and has been for the last millenium. I will pray for you. Early on in my Christian life I was a catechumen in the RCIA and was fortunately delivered by Evangelicals, who told me, yes, indeed, it was not necessary to pray to “our mother, the earth,” as I was instructed to do by a nun, backed up by a priest. The Roman church is not just full of sinners. It IS sin, with a few lonely Christians here and there trying to redeem it, for the sake of a missed latin ritual.
