The Bible is a Catholic book.
Protestantism is a heresy. That's not to say all Protestants are heretics, most just don't know any better.
A great deal of modern catholics also have very little to be proud of in terms of faithfulness to the faith.
As it stands, I think we should be reunited against bigger enemies, ie. atheism, redefining marriage to accomodate same sex couples, abortion, et cetera.
An atheist told me once, how could he be a Christian when Christians couldn't even agree? I told him Catholicism was the only safe bet.
We were here first.
Jesus Christ founded Christianity; and this division was created by those leaving the faith as well as by Catholicism. Had we been living our faith as we were meant to, those groups which fell away would have returned centuries ago. As it is, if it weren't for different Protestant denominations, many would have no Christian fellowship at all - which has been God's intention always - we were not created to live in isolation. It is absolutely impossible to keep our faith without support of those also believing it - and our church simply couldn't give a crap about how many fall away. It's been going on my entire life, and they know it. Our clerics would rather 'annul' a marriage than help the right people find one another in the first place, it makes their job easier. And they'd rather see young people fall away from their faith (most likely to atheism) than talk about the hard topics like SEX. Wouldn't it have been better for them to have been brought up Protestant?
I'm not attacking our faith, its beliefs are correct, it's practice is what's been slowly killing it and the faith of so many. I have responded here for the most part as I know many very good Christians who are Protestants of different denominations and they live by their faith in Christ; socialize with others in their faith; are involved in many things. This isn't just seniors either! There's all sorts of stuff for young people and members of all ages and it is not a rarity to see their Christian young people practicing morality (no sex until marriage); whereas if we can even find an adult social group we have to hit off the stalkers/mashers with a stick.
Being here first doesn't win the argument, as they are Christians too. Not only that; how can we say we are His followers if we don't live His teachings; but only talk them? I thought I'd have done several missionary trips by now (would have had I been Protestant. I'd also have been married; and could have converted later.) A lot of Protestants know what they believe in; they also can see what we believe in and likely can't understand why we think Christ's only teaching was the Last Supper; and if we truly believe in Him as they've read we do - that we can have the scandals we do and have so many of our members fall away annually.
Actions have and will always speak louder than words.
