Orthodox Bishop Hilarion Alfeyev: "To be a theologian means to have experience of a personal encounter with God through prayer and worship."
This is a very helpful way to explore a topic. It's interesting to see how others are developing applications and this certainly has the interaction benefits you mention.
Thanks for sharing.
