One can pray everywhere and anywhere, yet there are places where prayer ends its natural climate; those places are churches, fulfilling the promise; ‘I will make them joyful in my house of prayer’ (Is 56: 7).
A church, once consecrated, once set part, becomes the dwelling-place of God. He is present there in another way than in the rest of the world. In the world he is present as a stranger, as a pilgrim, as one who goes from door to door, who has nowhere to rest his head; he goes as the lord of the world who has been rejected by the world and expelled from his kingdom and who has returned to it to save his people. In church he is at home, it is his place; he is not only the creator and the lord by right but he is recognised as such. Outside it he acts when he can and how he can; inside a church he has all power and all might and it is for us to come to him.
When we build a church or set apart a place of worship we do something which reaches far beyond the obvious significance of the fact. The whole world which God created has become a place where men have sinned; the devil has been at work, a fight is going on constantly; there is no place on this earth which has not been soiled by blood, suffering or sin.
When we choose a minute part of it, calling upon the power of God himself, in rites which convey his grace, to bless it, when we cleanse it from the presence of the evil spirit and set it apart to be God’s foothold on earth, we reconquer for God a small part of this desecrated world. We may say that this is a place where the kingdom of God reveals itself and manifests itself with power.
When we come to church we should be aware that we are entering upon sacred ground, a place which belongs to God, and we should behave accordingly.
~Archbishop Anthony Bloom, Living Prayer
