Sister Elizabeth Liebert took over as dean of San Francisco Theological Semi nary on June 30, becoming the first Catholic nun in that post at a Presby terian Church (U.S.A.) seminary. Liebert has taught at SFTS for 22 years and was the first Catholic to receive tenure at the 138-year-old school. “We are particularly pleased to be attaining a historic ecumenical milestone,” said SFTS president Phil Butin. “Behind me is my whole religious community,” said Liebert, a member of the Sisters of the Holy Names of Jesus and Mary. “We’re always talking and praying.” The PCUSA has ten seminaries in the U.S.
