St. John O'Sullivan was placed in charge of the mission in 1910, at which time its community was scattered and its buildings in ruins. He set about rebuilding the parish community as well as restoring the old facilities. The Mission was accorded full parochial status in 1918 as the
Mission Church San Juan Capistrano. The Serra Chapel, the oldest standing church building in California and the only extant building where St.
Junipero Serra is known to have said
Mass, was used for services, as the Mission's original stone church was destroyed in an
1812 earthquake. Various efforts had been made to restore the church over the years, but had only caused further damage. O'Sullivan, who would serve as pastor until his death in 1933, had thought to construct a new parish church modeled on the old stone church, but never realized his idea. The modern case for a new parish church was taken up by Fr. Paul Martin, who was named pastor in 1976. By this time, the area Catholic population had grown considerably, and the Serra Chapel was inadequate to the needs of the parish. encompassing pledge drives and donations from mission visitors. ==Design==
