Protestants are Protestants.
Catholics are Catholics.
In either case, their churches tend to be split, as I stated in the article. I’m sure there are “liberals” and “conservatives” in each, who prefer to think of their beliefs as “mainline.”
However, I hope none are bigoted or haughty enough to dictate which handfuls of tares, and the wheat along with it, may be uprooted, and called “gone from the world of Christianity.”
Pleasant pondering with the Lord. I suggest the entire article. Then again, I wrote it. ;-> Also, the comments beneath it.
“Mainline” is a technical term that refers to certain denominations, e.g. UMC, the Episcopal Church, PCUSA, etc. The Mainline denominations are a theological sewer. Remember, Paul constantly warned againsdt false teachers creeping in among us. We have to be discerning.
“However, I hope none are bigoted or haughty enough to dictate which handfuls of tares, and the wheat along with it, may be uprooted, and called gone from the world of Christianity.”
You don’t have to be either bigoted or haughty to exercise discernment or spot obviously false teachings. ECLA and the Episcopal Church have, eg, adopted officially false teachings at a high level. The teachings are directly contrary to scripture that spans thousands of years and their doctrines have been adopted with knowledge of that scripture.
Paul did not suggest we listen to false teachers. He didn’t run around calling them “Christians” so as to be PC. As to “matters that may be disputed,” we should not create doctrinal battles (Romans 14). But as to the clear lines in scripture, Paul fought like a lion.
