The Lord has told me a few things quite directly. I can rely upon those things, even though it not be reasonable of me to ask for anyone else to do so, since it was of a personal nature -- yet still not some grand new theological outlook -- not at all. In the Scriptures we can all of us find far more towards what the Lord calls us to be. I do flatly refuse to elevate teaching of the RCC to be on level with the written Word of God, though, and always shall. Unless the Lord reveal to me as powerfully as He confirmed to me the Bible was true ---that what the self-vaunting so-called 'Magesterium' variously proclaims is equally true in all that it professes --- then forget it. Not only that, but I will not hesitate to continue drawing distinctions between those, advertising that distinction and difference as loudly and widely as I can. That's my own service towards the Lord.
Among all of what the Lord has impressed upon me, and what can be found in Scripture, nowhere have I been told (other than by Roman Catholics) that I must become a Roman Catholic -- or else --- inevitably risk being "a bearer of His name only" etc.
But nice try. What you just said (as far as the risk factor goes) applies to membership of most any ecclesiastical organization.
Among various and sundry dangers for how one could be led amiss of what He calls us to be, the more religiosity there is, the more danger there is that one could be mislead by THAT very thing --- and not only amid Catholicism it bears to be said.
Your difficulty is that you perceive that Catholicism is a denomination like any other. It is not.
It is the Church that Christ Himself founded, entrusted to the Apostles, who then entrusted it to the Apostolic Fathers, the Church Fathers, and down through the ages to today.
And that claim is provable. Because Lutherans did not exist before Luther, Calvinists did not exist before Calvin. But Catholics were present from the beginning.
