A diligent student, he especially excelled in the Spanish language and participated in Fr. Jimmy O’Connell’s summer ministry to migrant workers in the Midwest and Western states. He was ordained to the priesthood by Auxiliary Bishop Roman Atkielski, DD of Milwaukee on July 2, 1964.
He was charged with presenting a weekly Justice & Peace forum, a commitment he honored throughout his life. Fr. Ricardo initially provided sacramental ministry to the Yaqui Indian tribe, which has communities on both sides of the border between Arizona and Mexico. Within two years, he was appointed to the Redemptorists’ Mexican American Inner City Apostolate, an experimental community of confreres living in the Tucson barrio that quickly evolved into a true social ministry commitment. Although the Inner City Apostolate was disbanded in 1972, Fr. Ricardo’s ministry in the barrio continued for five more decades.
