"Her bag contained some cash, her car and house keys, and all her cards.
"Fortunately, she had a spare set of car keys, but she has had to get the locks on the doors at her home replaced, along with all her cards."
Rev Dymock said it was an extremely disappointing thing to happen.
"Theft can happen anywhere and church is obviously not a sacrosanct place for some people.
"I did not recognise the man as a regular church-goer and it would probably be wise for other church parishioners to keep an eye on strangers in their churches."
A description of the man was given to police and they have an inquiry under way.
