In the end, who gets to make the judgement call on if someone is following the "true" Christ?
If you are a Mormonophobe any one who doesn’t believe precisely as you do is condemned to hell.
God made that judgment call a long time ago...
We cannot question if an idvidual who claims Christ with in our midst is a Christian, but if they are practicing some very unchristian ideas and worse teaching such then we are required to point that out...
By the standard you are trying to hold, a Muslim can walk up to me say he is a Christian and you would have me accept that as Gospel truth.
BTW I find it interesting you are avoiding my question about if you believe in your articles of faith...
