It was not before September 2004, however, that the diocese obtained a title deed to the land on which the cathedral stood and hence it was only in that year, under Theo Naledi, that the cathedral was finally consecrated. Mallory resigned from Botswana in 1978 and was, from 1979, Assisting Bishop in the Diocese of Long Island. He was soon after elected to the new Diocese of El Camino Real, California, and appointed in 1980. Mallory served the diocese until his retirement in 1990. While Bishop Mallory's longtime interests and specializations had been in global affairs, and in multi cultural and multi religious practices, more recently he had been developing and teaching on ministry to the dying. Bishop Mallory died on April 4, 2018, in Monterey, California.
