If the “Church” had some faults, that is if the “Church” promulgated error or sin, we have every reason to reject it because it contradicts itself as one, holy, catholic, and apostolic. The error here lies in the telling: the Church is the Body of Christ, the goodness of all its adherents from Christ’s time—not the accumulation of beliefs, behavior or misinterpretations of some of its practioners. Individual members, priest, nuns, bishops, cardinals have sinned or otherwise misled the faithful; and some popes have led less than exemplary lives, but not one has been contradicted or overruled by a successor in matters of faith and morals. Thus, even if all the old nun-stories are true (which I doubt), it doesn’t matter. Catholicism, like math or English or chemistry or medicine, can be and often is inadequately or incorrectly taught. That misteaching can’t represent or disqualify the whole subject.
As you say, official teaching is accessable.
However, getting back to the article, tolerance is not and never has been a Christian virtue. The author confuses tolerance with charity while neglecting the Works of Mercy, Corporal and Spiritual.
I agree, good post. Said better than me.
