Many people define themselves by their religious beliefs (or lack thereof), which is why it deserves the spot as the number one religious debate of all time. It seems to me that everyone, no matter what gender, nationality, ethnicity, or age has an opinion on this topic, and they love to share it.

I believe the biggest debate of all is the debate by each religion as to why they are the true way. It is also the basis behind most of the holy wars throughout history and the justification to convert other peoples to their religion.

I do not think it is a cult but a group of people who do believe it works for them and they arent hurting anyone as I see it.

I think it is peaceful but like all things can be taken to levels or terror and deceit.

Christianity claims that Jesus Christ was the Son of God who was sacrificed to absolve believer’s sins so that Christians could receive eternal life. The Christian Bible teaches of many miracles performed by Jesus of Nazareth and of his resurrection from the dead. However, many people dispute that he was the Son of God and that the writings of the Bible are embellished stories chosen by the Church to further their mission. Thoughts?
