It is all fine to agree to disagree, yet your post crossed the thin line between informing and preaching.

Such language like:

"They Are Nothing More Than A Modern Day Sect Of Christians And Should Prepare Themselves For The Coming Of The Messiah ."

"Muslims Seem Set On Trying To Defeat The Power Of Christianity And Its Ability To Convert People World Wide."

It wont be tolerated here because it is no longer informing but comes off as preaching.

As for your question, of course Allah's Sunnah is Al Qu'ran and the Prophet stated of all these sects the 'saved' sect are those who follow the Qu'ran and his Sunnah.
