Th Church is a Church of sinners in need of a Savior. There is no shame or contradiction in that.
Wow. What a pathetic argument for looking the other way regarding the pederasty practiced by RC priests which is simply one more symptom of Rome's many doctrinal errors...
The "assumption of Mary bodily into heaven; regarding priests as "another Christ;" the confessional booth; the sacrificial alter; praying to saints; veneration of Mary as "co-redeemer;" baptismal regeneration; five extraneous sacraments; the papacy; limbo; purgatory; the denial of the priesthood of all believers; the misunderstanding of sanctification with justification; and a works-based salvation which obliterates grace.
To name but a few.
But the Church's greatest sin is in not accepting the gospel of Calvin and recognizing the inherent superiority of the election of his followers and their sinlessness. So in reality your petulant little anti-Catholic tirade is all about you. That really affirms Matthew 20:16!
