Lethargic Man (anag.)

I read your book and something caught my interest.7 Disciples who wanted to form the church in the gentiles.When I visited Rome we visited the Catacombs where the murial's on the walls were of the last supper each one only showed 7 disciples,I asked why and was told that seven was a holy number.I am now beginning to wonder if in the early days of the Christian church two groups,7 disciples(away from the jewish church and its history) and 12 disciples (wanting to remain in the original church.Why did the twelve win the argument? I am a 66 year old man who is not an academic. Yours with interest Michael Tatum mtatum@fsmail.net
