Well, the other post I made, on the Catholic Chronicles is exactly what you are looking for. He takes Catholic dogma and compares it to the Bible on essential issues. Keith Green spent months going through Catholic doctrinal papers and catechism to make this.
The problem is most of us do not have the time to do this. Or the space in this forum. So what you mistake for indifference, may in fact just be time constraints. Plus, why should we spend months researching the Catholic Church, when simple things prove it wrong!? Anyway, the articles are long and thorough. You may disagree with them, but it is where I am coming from. I read them soon after I was saved. (And just so you know, Keith Green also did some articles on the problems in Protestant Churches! He wasn’t biased when it came to defending Biblical Christianity.)
Further, regarding the early church fathers, I have read a lot of the Didache in Greek. Some of it was just quoting or paraprhrasing the Bible. some was commentaries on the Bible. And some of it was just made up stuff. Like “a traveling evangelist who stays in a town more than 2 days is a false prophet.” So, although the early church fathers can confirm things in the Bible, they are not reliable for doctrine at all. They so often go far beyond the Bible. And so we cannot base our doctrine on the early church fathers, especially when they go far beyond the Bible. They did not meet Jesus, and they are not inspired, although they can be valuable to study.
As for the apocrypha - just no! Some of those books are just fiction stories, and in some cases, like 1 Maccabees, good intertestimental history. Others, like 2 Maccabees contain historical inaccuracies, leading the vast majority of Biblical scholars to outright condemn them as “ not inspired” or for use in doctrine. And that passage about praying for the dead - first, not right, it is found in a book with many historical mistakes. Second, hermeneutically speaking, you should never make a doctrine out of just one verses, ever! Even if it is in an inspired and canonical book, which 2 Maccabees is not.

Finally, in the interests of full disclosure, I am a pastor and chaplain, unable to work right now because of severe Rheumatoid Arthritis. I have my MDiv from a Baptist seminary, ATS certified! I am married with 4 grown children and 5 grandchildren.
So, here is a link to that post. There are links to all 4 articles in a better format than my copy and pastes!

PS. I forgot to mention I have read the complete apocrypha for my New Testament Survey course. Good to know Intertestimental literature!
