66. Holy Ground Problem What is a church or temple? It is a place of worship, spirit, contemplation, of course. But above all, from a human point of view, it is a gateway. A person comes into the world through the church. They leave it through the church. And, at each of the important thresholds of their life, they once again step through the church.
