Your job seems to be that of defacing the walls of Christendom by scribbling thereon impious graffiti and being a self-appointed and self-imagined expert opinion generator on matters Scriptural. You should know that it takes more than possession of some form of the Book and a few reading lessons to qualify as an expert. I certainly would be reluctant to trust my cat's grooming, my car's transmission or even paint job to one with such scant credentials. Did Jesus Christ mention you in Matthew 16: 13-19?
I gave you the Scriptural backing. For a devotee of YOPIOS, you are remarkably but understandably reluctant to try to back up your imaginings with Scripture itself.
When Catholics need your opinions as to our (and Jesus's) Church, I suspect that we will let you be the first to know but holding your breath waiting is neither practical nor recommended.
If you do not even qualify as "separated brethren," then you must be in much worse trouble than had been previously evident. I shall endeavor to keep you in my prayers. I do note that you have added a few more unsubstantiated editorials. You seem to be very long on uninformed opinions and very short on knowledge of the underlying facts.
I don't suppose that you care to identify which particular "church" or denomination has obtained your personal allegiance and how you have determined (with specifics) that it is somehow the true church.
Evidently he's a Supralapsarian Calvinist of the old school (as opposed to slightly more moderate Infralapsarian Calvinists). That can be found in several different sects, such as the Scottish Presbyterians of the 16th century or in Dutch Calvinism of the 17th century, but is getting pretty rare.
Much of this was discussed in interesting detail at the Synod of Dort.
