Of course they did. That's why you had to have a Church Council. So then when the Council came to a decision, it was authoritative. It became part of the "official teaching," since the Council of Jerusalem was acting as the Magisterium, the teaching office of the Church. Then either the disagreements ended, ~or~ those who persisted in disagreement could readily be shown to be opposing the Holy Spirit and the Church. The relevant Scripture:
What the Church teaches on matters of faith and morals is perfectly clear. So if any pastor, pundit, bishop or best friend teaches differently, they are teaching erroneously --- contrary to the Church and the Holy Spirit --- and you can document it.
"Are all of your Church;s priests in agreement?"
Yes they are, IF they are teaching what the Church teaches.
"On pedophilia? On homosexuality?"
Yes, those sins ae pretty much addressed by the Catechism: starting with this, and the following paragraphs.
"Is the Pope elected by a 100% margin the very first time a vote is given?"
Why do you even ask this? Of course not. They usually have to go through several rounds of voting. I have never asserted --- nobody has ever asserted --- that all Catholics have the same opinions, or that we are all individually infallible (free of error) or impeccable (free of sin). That would be a manifest absurdity.
What we do say is that the Magisterium (teaching office) of the Church cannot propose errors as binding de fide on the whole Church. A shorthand way of saying that would be that the "Ordinary Magisterium" of the Church --- e.g. what's in the Catechism --- is true and correct, even if "Catholic" Cardinal Carnal and "Catholic" Congressman Criminal disagree.
"I mean you put an impossible bar up there to judge an individual but ignore it when it comes to your own Church. I don't know whether to label that hypocrisy or a straw man argument or both."
Neither. It's much simpler than that. I would say you probably have an erroneous idea of what the Church actually claims as authoritative.
I would say you probably have an erroneous idea of what the Bible actually claims as authoritative.
