celcius,
so you have heard of st.thomas, no celcius it seems that a 'true christian' is again down to interpretation. eg. roman catholic (true christian) acc. to roman catholics etc.etc.
i really think it's derived from the original follower's of Jesus, a breakaway group from Judaism and since over 32,000 groups of religion have been borne.
those religions i believe have made their own interpretations of the way to God when there is only one way, God's way and that's through Jesus, but it is not a religion, it's love and trust which we've seen little of since before he was murdered. Tom.
