I am a Christian. I think religiosity has it's problems. So I tend not to call myself religious. That said, doing something religiously could just mean doing it routinely and for a meaningful reason. We all do that. But as far as spiritual beliefs are concerned, religiosity can get in the way of the spiritual. It can limit the Christian life to Sunday, for example, or limit it to within a church building.
I belong to the church, and I meet for church every Sunday in a primary school building. My local church is purposely informal, is full of people my age, and I love it! It is like being in a family. However, I do sometimes get frustrated that I've not made close friends, despite getting on well with everyone generally. This is not a criticism of the church, people invite me here and there, and make friends on facebook etc., are genuine, accepting, loving etc etc..but it a common occurence wherever I go and it's something I'm working on.
