As a former Catholic (now an Evangelical Christian), I am all too familiar with the false teachings and un-Biblical traditions of the Roman church. I disagree with them.
But either Graham or his son Franklin never compromised the Gospel to fall in line with those false teachings.
Ravi Zacharias, an acquaintance of mine and the man I admire more than any others I have ever met in my life, spoke to the Mormon church. He did it to bring the true Gospel message to them. Should he be condemned?
Getting to what you originally started here (i.e. political support for Cruz) - I don't think he would have made a bad President. He certainly would be infinitely better than what we had now. But he cannot win the nomination, and if he did, I think Hillary Clinton would have destroyed him in the general election. Only Trump can defeat Hillary.
you should have read the details, he was agreeing with them, saying they brought the true gospel
Did Zakarias say that in Utah?
