"Be not carried about with divers and strange doctrines. For it is a good thing that the heart be established with grace; not with meats, which have not profited them that have been occupied therein."
~ Hebrews 13:9

Major Heresies

For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ.
2 Corinthians 11:13

These are what one may call damnable heresies, or heresies that affect one's salvation. If one does not believe in the Jesus Christ of the Bible, he is not putting his trust on the right God but of one he fashioned after his own image. Do not fall into these traps!

NOTE: As of current time, I haven't gone about making the pages yet. Please be patient. Thank you.

False Churches

While there's no shortage of heresies and false churches out there, here are a couple that one can look into.

Roman Catholicism: Was it the original church? The great counterfeit mother harlot
Greek Orthodoxy: What appears to be the third wheel is just another leg of the same body
Seventh Day Adventism: Taking the words of a woman quite far
Latter Day Saints (Mormonism): When an angel gives you a different gospel, American edition
Jehovah's Witness: More like Jehovah's False Witnesses

False Religions

These do not claim to be Christian, but are nevertheless major religions out there in contention with Biblical Christianity, and also need to be written against.

Judaism: Are they really the chosen people™ of God?
Islam: When an angel gives you a different gospel (the great CIA operation of old Arabia)
Buddhism: Would you like eternal death or eternal life?
Hinduism: Curry-flavoured paganism
New Age: Not all roads lead to the same place (most do though, and not where you would want to go!)
