English: By late 1964 Mass was regularly celebrated in the new church, though everyone remained patient with the fact that all the inner details were far from complete. Everyone shared pride and ownership of the new building. By the mid-1960s the development of homes in the area was peaking. Father Rielly was anxious to build up more capital for continued expansion, so held an auction of the church's Adobe property. The winning bid was $51,000—the exact cost of the new location he had purchased just six years before.

A spirit of goodwill and friendship was apparent in the parish community. Parishioners shared a common goal and worked together toward it. Both the Men's Club and the Women's Guild hosted various social activities and bake sales through the years to raise even more money to offset the parish debt.

The parish enjoyed continued growth of its programs throughout the years of fund-raising and construction. A more mature CCD program evolved after the rectory building was completed.

While the parish was involved in major growth, the Catholic Church was embarking on a period of unprecedented change. Pope John XXIII had convened Vatican Council in Rome for the purpose of spiritual renewal within the Catholic Church. Among numerous tasks accomplished during the meetings, the Council members traced the rich heritage of the faith and determined that, throughout its history, the responsibilities of the faithful had gradually been given over to the clergy. Few duties remained entrusted to the laity. At the closure of Vatican II in 1965 the Council documents sought to reinstate the rights and responsibilities of all baptized members of the Church. Put simply, the laity were asked to respond to the call of Baptism, which was to share in the priesthood of Christ, and in the ministerial work of the Church.

In direct response to Vatican II the community of St. Peter formed a Parish Council. Throughout its brief history the work in the community of St. Peter seemed to already be a reflection of the newest teachings of the Church. Lay persons around the world were challenged to become more involved in their parishes, in an effort to recognize that church is not the building; rather, the church is the people. It was not surprising to surmise that the parish of St. Peter was a parish "ahead of the times."
