What is it with you? How is that relevant and where did i claim I was IFB? That was were you diverted from after my reproof that
"again, your preoccupation with particular churches presumes that i and other evangelicals are promoting a church, or that the one true church is one particular denomination, which is false. Only the body of Christ is 100% constituted by believers, while its varied (and they were in Scripture) visible churches have never been made up of 100% believers for long, nor did they realize comprehensive unity, or could presume to maintain complete freedom from any error.
But God always preserved faith, but not by a perpetual infallible magisterium, though magisterial authority has its place, but God often raised men from without the magisterium to correct it, and or add revelation, and preserver it. And thus the church began and thus has faith been often preserved. "
And that i basically ID as nondenominational is irrelevant as to the issue of paedobaptism, as is your preoccupation with denominations, as it is not I who am preaching a particular church as the OTC, and it is RCs who find fault that we have particular infallible church which we are bound to assent to as supreme as a RC must to Rome.
Thus what you need to establish is that perpetual magisterial infallibility is essential for a church to be true, and to discern and preserve faith, with the historical stewards of Scripture being that magisterium.
And that those who hold most strongly to the most fundamental distinctive of the Reformation, that of Scripture being supreme as the wholly inspired and accurate word of God, are less unified in basic values and beliefs than the fruit of Rome. And that paper unity constitutes what one really believes.
Otherwise what is of God is subject to being established upon the weight of Scriptural substantiation, though that allows for competition, and a harder path to unity than the premise of assured magisterial veracity, and thus implicit assent.
