The achievements of the past are a means to show Christians the way forward. That was the message from the Archbishop of Canterbury on Sunday to parishioners in Tenby.

Dr. Rowan Williams led the service celebrating the 800th anniversary of St. Mary's Parish Church.

In his sermon, he paid tribute to the many people down the ages who had shaped Christian mission in the town.

"The church is a mark of the gospel," he said, "and the spirit that lives on here has shaped the way faith has made a difference. Today we are supported by all our yesterdays; past lives can be real now. Tradition is the Holy Spirit taking us forward."

After the service, Dr. Williams joined the hundreds of worshippers who attended at a reception on the church lawn, signing autographs and posing for pictures.

Among them was Lowri Evans, of St. Mary Street, Tenby, whose plaster cast on her broken arm now bears the signature +Rowan.

He was also presented with a commemorative plaque marking his visit by members of the church's Sunday Club, who performed during the service.

The service also remembered local resident John Greenhalgh, a long-time friend of the archbishop, who had originally issued the invitation to Dr. Williams to visit Tenby, and who died last year.

Rector of Tenby, Rev. Andrew Davies, commented afterwards: "It was a great and inspirational occasion for all who took part and we were all proud of Tenby that day."
