As if the Protestants are doing so much better.
Not all, but God always a remnant. All you have to do is sift churches by use of Scripture.
There is a whole website dedicated to it: 9Marks.
And there we have it. No human is going to be flawless, whether he call himself Protestant or Catholic.
So, IMO let’s work on unifying the one Christian church, simultaneously on foundation of 1 Corinthians 5:12 work on corrective action; and for those “outside” only evangelization … and worry less about whether Pope Commie or Pastor Wokechurch is more wrong.
