You think Catholics never hear horrendous sermons with misinterpreted Scripture? Puh-leeze! Still, it doesn’t often happen because even priests with a dissident agenda are deeply trained in Scripture, theology and philosophy.
The difference between much Protestant experience and ours is that one preacher is not the whole ballgame. People get nervous about the concentration of authority in the papacy. But it isn’t really concentrated. The teaching of the Church must, and does, flow from the font. The pope is a guardian. Doctrine builds cautiously from doctrine, always tested by Scripture and through patient (well, not always “patient” but at least thoroough) deliberation, often over centuries. No apparently “new” way of thinking may contradict Scripture or the deposit of faith.
If you get a maverick Priest, there is recourse to the bishop. Orthodoxy resides in a much broader base than it does for most Protestants – even for those confessional Protestant groups which have a hierarchical organization, such as Lutherans, Presbys, Methodists. For all of these groups the foundation on “scripture alone” leads to, “My Holy Spirit can beat up your Holy Spirit!” Split, split, split – because I am following the Holy Spirit, and you’re not.
And now we have the comprehensive and seraphic
Catechism of the Catholic Church*. *If you’re hearing something from the pulpit that sounds peculiar, you can check it against an authoritative source.
This is an accusation often leveled against the Catholic Church as well. To this I can only say that “rules” arise only in response to a need. Catholics don’t write a rule unless there has been a problem which that rule addresses. I suspect that is true for Protestants as well.
I don’t know about the legalism of Protestant traditions, but I do know that
canon law in the Catholic Church is really just a means of rendering into uniform, world-wide, practicable terms the way in which the fundamental principles of the Gospel can best be promulgated and lived out. When you sit down calmly and study Canon Law, each “rule” addresses a specific point of the day-to-day life of the Church. It can be quite illuminating.
