"He was very sad to be leaving the area and seeing the suffering of the locals he had come to love," Mr Morley said. "But we are relieved that he is in a safer place now and look forward to a call - maybe tonight."
Mr Morley said the family were also pleased that church humanitarian aid had reached Leyte.
Ezra had followed in his parents' footsteps by taking up a missionary posting and in preparation had travelled to a missionary training centre in Utah, where he learned some rudimentary Cebuano dialect used in the Philippines.
"He now speaks three dialects," Mr Morley said.
He expects his son to return to complete his missionary posting to Tacloban when the time is right.
