In the spring of 1974 Bishop Francis J. Green, of the Diocese of Tucson, made the request for a Christian renewal center to be established in Cochise County, the southeast corner of the diocese.

Abbot David Geraets, O.S.B. of the founding Benedictine Abbey, Pecos, New Mexico, asked Fr. Louis B. Hasenfuss O.S.B. to begin the project. He arrived in St. David from Albuquerque, accompanied by Paul Meuller and Steve Stevens, on September 3, 1974. They settled in on the 92 acres property. Maxine and Larry Lee, a married California couple, and Fr. Clark Moore, a Tucson Diocesan priest, were there with Marty Martinez. From this nucleus the Monastery grows today.

On December 12, 1974 the ground was broken for Our Lady of Guadalupe Church, with Bishop Green presiding over the historic occasion. He also presided over the church dedication on June 24, 1981.
