What do "Christians" mean when they use the word "Cult"? Often a better term would be "Christian Cult"
By "cult," we mean a group, religious in nature, which surrounds a leader or a group of teachings which either denies or misinterprets essential biblical doctrines.
Christians define the general word "cult" to mean a group of religious people who follow teachings and practices that deviate significantly from historic Christianity and the central doctrines of the Bible.
A cult is a religious perversion. It is a belief and practice in the world of religion which calls for devotion to a religious view or leader centered in false doctrine. It is an organized heresy. A cult may take many forms, but it is basically a religious movement which distorts or warps orthodox faith to the point where truth becomes perverted into a lie.
One way to define a cult is popular in evangelical Christian circles. From this perspective, a cult is any group that deviates from the orthodox teachings of the historic Christian faith
