For the Altar of Repose I used a very nice wooden tabernacle I had been given some years ago (from an old convent). The tabernacle used here before I came is a very heavy, large metal one with a brass door. I have been using that to store the holy oils. Because "my" tabernacle is wood, at the end of the watching I decided, for security reasons, to place the Blessed Sacrament in the old metal one in the sacristy. There was nothing wrong with the key or the lock.
Today, when I came to bring the Blessed Sacrament into the church during the 3.00 pm service, I could not open the door of the old tabernacle. The lock would not budge. I decided to bless the key and the lock. After about three more attempts, the door opened. When I went back afterwards to look at the door, the key was not bent, but when I put it into the lock it behaved as though it was bent. Clearly something had happened inside the lock itself. I am puzzled as to how this happened, and thank God that the door opened so that I could distribute Holy Communion.
