As I recall, you started this thread (on ***Catholic Answers Forums ***in case you missed the forum title) asking for an “accurate definition or description of what constitutes a Christian.”
As mercygate pointed out, baptism IS one of the constitutive acts of the Christian faith.
As wisdomseeker pointed out, Jesus built a Church not churches with many different interpretations of His Word.
Seraphim pointed out that you are ignoring those who are trying to teach you something, and/or you have not liked what you have been reading.
And of course it was St. Augustine who said **“I should not believe the Gospel except as moved by the authority of the Catholic Church.” **
Would you rather we just post in LDS fora and blogs explaining how any definition we could come up with of what constitutes a Mormon is somehow “better than” any definition originating from Salt Lake City?
Actually, zerinus’ point should not be trivialized: “Because the Catholic Church says so!” just does not close the case for those who have genuine reservations.
Although, as you well know, history and the paper trail support the Catholic position, many people truly believe that SOMETHING MUST BE FUNDAMENTALLY WRONG WITH THE HISTORICAL RECORD because they so strongly believe that the Catholic Church cannot possibly be the Church Jesus promised to build.
So you get theories like that espoused by R. C. Sproul, that the need for an identifiable church “falls away” after the closing of the scriptural canon, when Scripture becomes the only thing necessary. Or you get apostasy theories, as with the JWs and the Mormons, or you get persecution theories
Trail of Blood] where the “true” church survives underground despite persecution by the Catholic Church, only to re-emerge in all it’s unspoiled Protestant purity in the 16th century.
zerinus and I strongly disagree on the point that part of the definition of Christian must include the teaching office of the church in question. The Great Commission (to the Eleven) included the authority to TEACH. That means teaching the truth about God. Therefore, what any individual person may believe or understand, though important, is more importantly tied to the family tree of the Church through which he professes his faith in Jesus Christ.
I doubt that the Last Judgment is going to take the form of a theology quiz for most of us, but pointing in the direction of a correct understanding of the Godhead does point us toward the truth (and we all know Who that is). The troops on the ground may not need to know all subtleties but the generals better know where the caravan is headed
for the sake of the troops on the ground. A small error in the beginning can become a catastrophic misconception further down the line.
As zerinus points out, ALL of us have our ditherers. Catholics, Protestants and Mormons all have their share of folk who silently dismiss the ‘party line’ and live in their own little world. I have an ex-Mormon friend (not at all hostile to his upbringing) who tells me that many Mormons simply wink at certain teachings because their lives are so tied up with the family and social support structures for which the Mormons are justly respected.
