It's come up several times in discussions and debates on this forum. People will be arguing about Christianity without having a set definition. I have seen people claim that Christianity is accepting the entire Bible as fact, only the New Testament, only the Gospels, and some strip it down even less than that.
What I want to know is, what is the bare-bones definition of Christianity? The definition that if you do not adhere to it you cannot legitimately call yourself a Christian. Must you believe Jesus existed? That he still exists? That the Bible is true? Must you believe in God? Does the story of the virgin birth matter? Etc.
Anyone who answers, please check your answer for any hidden suppositions and add them to your answer. I'm tired of people posting oversimplified definitions.
Christianity, from the latinized Greek term Khri‧sti‧a‧nos′, refers to followers of Christ Jesus.
“It was first in Antioch [Syria] that the disciples were by divine providence called Christians.” (Ac 11:26) The term was current around 58 C.E., for King Herod Agrippa II reportedly said to the Apostle Paul:
“In a short time you would persuade me to become a Christian.”—Ac 26:28.
Christianity is 'technically' a Messianic Judaic religion. Thats how it began. They were jews who believed the promised Messiah (as prophesied in the hebrew scriptures) had arrived. They put their faith in him as the one sent by God to save mankind from sin and death. They were all followers of the Mosaic law, they were all jews to begin with and the New Testament writings are their way of explaining how the prophecies of the hebrew scriptures & promises concerning the Messiah were fulfilled by Jesus, or were soon to be fulfilled (not everything was fulifilled at that time - more was to come in the future). It was only later that gentiles were invited into the congregations and that was because God has poured his holy spirit on a gentile for the first time and spoke to the Apostle Peter about bringing in the gentiles.
To be a Christian one must accept that Jesus is God’s specially Anointed One and only-begotten Son, the Promised Seed who sacrificed his human life as a ransom, was resurrected and exalted to the right hand of Jehovah, and received authority to subdue his enemies and vindicate Jehovah’s name. (Mt 20:28; Lu 24:46; Joh 3:16; Ga 3:16; Php 2:9-11; Heb 10:12, 13)
They also have to view the Bible as the inspired Word of God,
absolute truth, and the only authoritative explanation of spiritual truth as Jesus did.
They must dedicate their lives to Jehovah, to worship and serve him, and then submit to water baptism as Jesus did. (Mt 28:19; Ac 2:38; 3:19)
Christians must be firmly resolved to uphold Gods moral standards as Jesus did. And one of the most important commands for a christian is to show 'love of neighbor' in every regard. These are the basics of being a christian...there is also performing the same work that Jesus and his apostles performed...that of preaching the good new of the kingdom. Christians must be preachers in keeping with Jesus command to 'Go and make disciples of people of all the nations'
