Quote:Who says it's a requirement? By what authority is such a claim made?
The claim is made because of the meaning of the word Christian. A Christian is a person who belives in Yeshua as the Christ 8it's in the root of the word "Christian"), the Messiah who according to the Bible is the son of the Biblical god. You simply like his teachings.
You can't claim to be a Canadian just because you like Canada. You need to be a citizen of Canada. Similarly, you can't claim to be a Christian just because you like the teachings of Yeshua. You need to believe in his divinity.
