A Michigan priest criticised for emphasising suicide in his homily during a recent funeral for an 18-year-old who took his own life has since apologised.

"As with any funeral, it was my intent to serve this family in their time of grief, but I fell well short of providing them the comfort they so desperately needed. Instead, I added to their pain. I deeply regret that, and I am sorry," said Fr Don LaCuesta, pastor of Our Lady of Mount Carmel Church in Temperance, Michigan.

He expressed his remorse in remarks to parishioners a week after the December 8 funeral of Maison Hullibarger, which received extensive media coverage. His remarks were released on December 17 by the Detroit Archdiocese along with its own statement of apology.
