Remember Jesus was the first to set up 'me v you' demarcation between Himself and the Pharisees.Part of what I'm saying is the practice and acceptance of unique rituals and one-time miracles as the line of demarcation between Christian and non-Christian is the breeding ground for an us versus them mentality ...
Jesus was by no means an 'anything goes' kind of guy!
Not uniquely. It is the second of two principles. There is a prior principle.That's what defines Christianity, but Thomas wrote it doesn't define Christianity.
Otherwise that would be tantamount to claiming that only Christianity preaches love of neighbour.
Nor do I see any issue in acknowledging Hinduism, Buddhism, Islam, Judaism, Native Americanism etc, when speaking in general sociological terms, such as the Golden Rule. But when I'm speaking in the Spiritual or Mystical sense, the 'one thing necessary' (Luke 10:42), then I am Catholic.Of course, Thomas has a point when he wrote he doesn't call himself a Buddhist. In one sense I see his point, but in another sense (from the Chrysostom quote above) I'm a follower of Buddha and Christ when I practice the Golden Rule, so I see no contradiction in calling oneself both a Buddhist and a Christian.
