In a recent e-mail from Frank Viola, part of his 'unfiltered' series, he talked about Christians and making connections. He made the point that Christians, unlike people 'in the world' seem to avoid making connections with relevant other Christians; for example, do Christian particle physicists meet to discuss their field as being Christians, and refine each other's thinking and practice? Frank's point is that they typically don't.
On the plus side, I was once in a group of Christians where we all had the same profession; we met, discussed, helped the junior members with their professional exams, and swapped professional practice ideas; was good.
Frank talks about setting such confrere groups, he calls them 'mastermind' groups; I'll think about same in my own field and place...could be good.
