The major thing that gets me with this service, was the processional. For her Golden Jubilee, HM The Queen entered to the magnificent "I Was Glad" which had a Section which glorified her Presence with resounding Vivats.
The Introit for this ceremony was a Te Deum Which...first is a rather well used piece of liturgy..and secondly...far more, outspokenly Christian.
The former mentioned going up to the House of GOD...but this latter piece talks about the compnay of prophets praising. Its definately not what I thought she would choose to use.
