Here is Joel Osteen claiming that Mormons are Christians. Many from the Seeker-sensitive Purpose Drive Church for the Carnal Nature of Mankind like CEO Steven Furtick actually defend this heretic all because Osteen is popular and has a very large church. It seems that large numbers must pardon heresy and false teachings as long as the "church" is growing: see Furtick's blog about numbers.

People following Furtick need to beware the poison water this false teacher is selling.
2 Peter 2:1-3 (New International Version)
2 Peter 2
False Teachers and Their Destruction1But there were also false prophets among the people, just as there will be false teachers among you. They will secretly introduce destructive heresies, even denying the sovereign Lord who bought them—bringing swift destruction on themselves. 2Many will follow their shameful ways and will bring the way of truth into disrepute. 3In their greed these teachers will exploit you with stories they have made up. Their condemnation has long been hanging over them, and their destruction has not been sleeping.
