After the death from AIDS of assistant priest Robert Kettelhack in 1989, the chapel in the east porch was designated the Diocesan AIDS Memorial Chapel, with a painting by Ian Faulkner of Father Damien over the altar, and a specially designed AIDS Memorial Book listing persons who have succumbed to the disease.
When it was decided to build an AIDS Chapel in the new Cathedral Center, Saint Thomas relinquished the furnishings. The altar is still used for the interment of remains. The chapel is now dedicated to Fr. Damien of Molokai. Fr. Damien is the 19th century priest who worked among the lepers of Molokai and has been adopted as the patron of people with AIDS. Rhett Judice designed the triptych replacing the Falkner painting. A copy of the Memorial Book remains.
This chapel also serves as the parish shrine for Our Lady Of Walsingham.
