Crikey!
Let me make this perfectly clear. Not one member of the Invisible Church of Christ (i.e., the body of True Believers in Jesus Christ) will ever spend a day in Hell. The institution known as the Roman Catholic Church does have members of the Body of Christ in it, but the institution known as the Roman Catholic Church is not the Body of Christ.
And Baptists (in spirit and in truth) have been around since Pentecost and many of those who call themselves Baptists are also members of the Church of Christ.
So get off your high horse. Salvation resides in Christ and not in some building in Rome.
I guess that Church was not only invisible, it was silent, until the appearance of the very voluble John Smyth in the early 17th Century
BTW, we Catholics can cite Early Church Fathers discussing The Catholic Church.
Please ping me to any, oh, I dunno, evidence, of a Baptist Church, say, prior to, oh I dunno, the 16th Century
