One recent Sunday morning I played the piano for our Anglican church. The piano is electronic and has buttons that will change to practically any style of music. For our purposes it is usually set for grand piano, which is nice for the hymns and musical responses.
What I did that morning was quite unexpected to me and to the rest of the congregation. Our minister said afterward that it was about the second most memorable thing that has happened in the history of the church, the first being when they almost burned down the building during an Ash Wednesday service.
We had moved into the second part of the service which is the Eucharist. During this time of preparation for communion we have a lot of prayers, and with some we sing responses. Every time I think about what happened I can't help but laugh, although at the time it didn't seem quite appropriate. (I'll just say right here that in telling this story I don't mean to be sacrilegious at all, but share an analogy.)
After praying a corporate confession of sins and hearing assurances of forgiveness from scripture, our minister leads us into the next part by using these words from the 1928 Prayer Book:
It is very meet, right, and our bounden duty, that we should at all times, and in all places, give thanks unto thee, O Lord, Holy Father, Almighty, Everlasting God. THEREFORE with Angels and Archangels, and with all the company of heaven, we laud and magnify thy glorious Name; evermore praising thee, and saying,
At this point we USUALLY reverently and majestically sing the following, also from the Prayer Book:
HOLY, HOLY, HOLY, Lord God of hosts,
Heaven and earth are full of thy glory:
Glory be to thee, O Lord Most High. Amen.
