You yourself have promoted "Rome Sweet Home," calling for Prot converts by specious Scott, and even worse, “The Protestant’s Dilemma” by the the misrepresenter Rose, reproved here , by God's grace, yet cannot tolerate our posting of such against RCs.
I don’t remember anyone telling you that you had to be a Catholic or go to hell.
Then that is due to you being a relative stranger posting here, and instead you are one of others who suddenly show up protesting the "anti-Catholic" posts while we who have been regulars here for years (by the grace of God), never saw them protesting the anti-Protestant threads that RCs have posted for years, which included the historical claim that one must become a Catholic to be saved.
Moreover, it is not necessarily holding to that claim that warrants a response by us in exposing the spurious nature of Cath claims, but simply promoting the elitist "one true church" is cultic and calls for rebuke.
I guess if there are a subset of annoying bigots in one part of the body of Christ then I’m not sure that justifies that behavior in another part. Let me know when you find a perfect church with no sinners.
Second, the blatant anti-Catholicism sticks out like a sore thumb. Suggesting books is evangelization. Shoving Scripture down people's throats, posting the same derisive material from thread to thread, is not only proselytizing, but is a negative presentation of faith in general.
While I as a Catholic believe the Catholic Church has the greatest deposit of Faith, there is an amount of truth in all faiths. We don't get most of the mean flak from our mainstream Protestant brethren, (with a few exceptions). The bashing is mostly from ex-Catholics, and independents who interpret the Bible for themselves.
As for salvation outside the Church, people tend to get stuck in the Council of Trent. That was hundreds of years ago. Check out Vatican II:
The Second Vatican Council speaks of salvation outside the Church in Lumen Gentium, nos. 14 and 16. Here are the pertinent sections from those two articles: 14. This Sacred Council wishes to turn its attention firstly to the Catholic faithful. Basing itself upon Sacred Scripture and Tradition, it teaches that the Church, now sojourning on earth as an exile, is necessary for salvation. Christ, present to us in His Body, which is the Church, is the one Mediator and the unique way of salvation. In explicit terms He Himself affirmed the necessity of faith and baptism (cf. Mk 16:16; Jn 3:5) and thereby affirmed also the necessity of the Church, for through baptism as through a door men enter the Church. Whosoever, therefore, knowing that the Catholic Church was made necessary by Christ, would refuse to enter or to remain in it, could not be saved. [. . .] 16. [. . .] Those also can attain to salvation who through no fault of their own do not know the Gospel of Christ or His Church, yet sincerely seek God and moved by grace strive by their deeds to do His will as it is known to them through the dictates of conscience. Nor does Divine Providence deny the helps necessary for salvation to those who, without blame on their part, have not yet arrived at an explicit knowledge of God and with His grace strive to live a good life. Whatever good or truth is found amongst them is looked upon by the Church as a preparation for the Gospel. She knows that it is given by Him who enlightens all men so that they may finally have life.
Defending your beliefs is one thing, but check out some of the posts on the site. I recently got called a troll! I consider the source, but honestly, we aren't kids on a playground; we just act that way sometimes- just about all of us. We, myself included, need to lighten up sometimes- but it's hard when people deride what you love most in the world, and the only thing that's worth living for in an otherwise horrific world.
God bless you, and may we all meet in Heaven!
