The Church of St. Martin is no longer Catholic. It is a desecrated Anglican church, and God is not there. Peeing on the floor of that building would be no different than peeing in a cow pasture.
St. Dunstan's Church was also stolen and desecrated by the Anglicans.
Let me ask those on this forum a related question on desecrated Churches.
A trad Bishop shows up at an old Catholic Church in San Francisco that has been sold to a commercial interest.
The altar tabernacle is boarded-up and
there is a “Star of David” above the sanctuary.
The Bishop ignores the church’s desecration for the past 50 years and promptly enters the sanctuary to celebrate holy Mass.
Since the Bishop did not bother to re-consecrate the church, was this Mass a sacrilege?
