factor behind his conversion is his research on what he saw as the key to the Bible: the covenant. This is a sacred kinship bond that brought people into a family relationship. God established a series of covenants and the new covenant established by Jesus Christ is an establishment of a worldwide family. He believes that Jesus and the apostles used family-based language to describe his work of salvation: God is Father, Christ is Son and the firstborn among brethren, heaven as a marriage feast, the Church is the spouse of God, Christians as children of God. This new family, according to Hahn, is headed by Christ and the Pope is his "prime minister" to whom he has given the keys of the kingdom, a process that he believes is also present in the Old Testament. Hahn writes that the Catholic Church, whose head is called "Holy Father", is the worldwide family described by the Bible and that the Protestant doctrines of sola fide and sola scriptura are not biblical because they are not found in the Bible. In his view, the Bible stresses charity and works as necessary for saving faith, i.e., justification, and, therefore, salvation. He also points to the Church as "the pillar and bulwark of the truth", quoting 1 Timothy 3:15. Hahn converted to Catholicism at Easter 1986 in Milwaukee, Wisconsin. He came to be called "Luther in reverse", from his wife's words. Hahn's wife, Kimberly, had a similar conversion at a slightly later date, entering the Catholic Church at Easter 1990 in Joliet, Illinois. Rome Sweet Home describes their process of conversion together. In Ordinary Work, Extraordinary Grace, he narrated the influence of Opus Dei in his conversion and what made him feel that Opus Dei was his specific calling within the Catholic Church: (1) its members' devotion to the Bible; (2) its ecumenism, since Opus Dei was the first Catholic institution to welcome non-Catholics as cooperators; (3) the upright lives of its members; (4) they were ordinary people, who lived theology; (5) holy ambition: "a devout work ethic"; (6) the practice of hospitality in answering his questions; (7) prayer: "They made time for intimate prayer every day." Current work Hahn founded and is currently the president of the St. Paul Center for Biblical Theology, a Catholic non-profit research and educational institute committed to the promotion of biblical literacy among the Catholic laity and biblical
