This type of argument is ultimately vain, as you well know. So long as the definition of a Christian is controlled by extra-Biblical philosophies or sources, there is no standard on which to measure each side of the debate. Mormons use an extra-Biblical standard based on what they claim is modern-day revelation. Most others base their definition on ecumenical councils centuries after the death of the Savior. If each holds to its definition, then all others are ipso facto “non-Christian”. (BibChr holds to the definition, apparently, of solely grace, solely Bible, which would seem to exclude the Catholic Church which believes in works and tradition. See how this kind of debate gets us nowhere.)
It seems a more worthy argument is to accept the standard of the discipleship that one follows the teachings of their professed master. However, this kind of argument hits many “acceptable” Christians full in the face because of the great diversity among practices such as baptism, priesthood authority, church organization, offices in the church, confession, treatment of homosexuality and extra-marital sexual relations, tithing, etc., etc. So that is also ultimately a difficult argument.
Best yet, let’s leave the definition to the Savior who will recognize all His people when He comes to reign on the earth again.
Color Country, regarding your tag line, consider Isaiah 55:8-9. Just a suggestion.
8 “For my thoughts are not your thoughts,
neither are your ways my ways,”
declares the LORD.
9 “As the heavens are higher than the earth,
so are my ways higher than your ways
and my thoughts than your thoughts.
Agreed - at least with this scripture. But really, what does that have to do with my tagline.
I suppose you think it wise to follow the so-called Prophet, Joseph Smith because God’s ways might be higher than you understand and so the provable heresies of his teachings should thus be ignored. If so, then my common sense would tell me that you believe in nonsense. Have a good day. :-D
