I went to a wedding on Saturday. It was superb, representative of the outstanding qualities the bride and groom brought to their marriage, and I could, but will not wax eloquent about the food at the reception, and the speeches which were, simply, outstanding.
Here I simply observe that the minister at the wedding, himself a relaxed leader of worship and minister of the Word, made the guests feel comfortable. He spoke to us twice before the service began. We received relevant directions (move to the front to allow for late arriving guests, where the toilets were), and up to date information (the bride was coming but was a little late). There was an element of humour in what he said - I think, in terms of making strangers feel at home in a church, we cannot underestimate humour as a means of drawing people together. But the humour was combined with clarity in his communication.
