I challenge anyone to even TRY to challenge this.
Then Martin Luther, the leader of the Protestant Reformation, was wrong as well. Luther believed in the Real Presence AND in the perpetual virginity of Mary, two items modern day Protestants dismiss. Somewhere down the line, the denomination Luther founded splintered into 33,000 sects all which have slightly different, more or less, interpretations on Scripture.
I choose to follow the church established by Christ that has not changed a doctrine in 2,000 years.
This does not mean that I think that non-Catholic Christians are not saved; I believe many are. I believe most Christians are good people striving to live Godly lives. We agree on so much more than we disagree on. However, the Eucharist IS important, and the Real Presence IS important. That's why I'm on this thread. I tend to avoid most apologetic debates until it gets serious.
Anyway, just thought I'd throw out the stuff about Luther. He basically agreed with virtually every Christian doctrine (because all Catholic doctrine was Christian doctrine until then) except he thought the current leadership was corrupt. It very well may have been, but the corruption of the few didn't destroy the Truth.
God bless.
