Thomas Weinandy

In 2017, Weinandy wrote a letter charging that Francis is fostering "chronic confusion", "demeaning" the importance of doctrine, appointing bishops who "scandalize" believers with dubious "teaching and pastoral practice", giving prelates who object the impression they will be "marginalized or worse" if they speak out, causing many faithful Catholics to "lose confidence in their supreme shepherd". Weinandy resigned from his position as consultant to the U.S. Conference of Catholic Bishops' Committee on Doctrine.

In 2014, Pope Francis appointed Weinandy to the International Theological Commission for a five-year term.

Pope Francis honored Weinandy with the Pro Ecclesia et Pontifice medal for his work on behalf of the Pontiff and the Church, one of the highest honors in the Catholic Church, in 2013.

Weinandy responded to a July 2012 article in Newsweek written by theoretical physicist Lawrence Krauss describing how confirmation of existence of the Higgs Boson particle could get rid of the idea of a supernatural creator permanently. "While the Higgs particle may help us in understanding the relationship between mass and matter, it does not explain why the Higgs particle itself exists," Weinandy said. "There must be a being whose very nature demands that it exists and, because of this, is able to bring other beings into existence."

In March 2011, Weinandy participated in a telephone press conference with scholars from Catholic, Protestant, and Jewish backgrounds the day before the release of Pope Benedict XVI's book Jesus of Nazareth: Holy Week. Weinandy said that Pope Benedict "sees Jesus as someone the world is longing to meet, and he’s doing his best to try to provide that opportunity."

In a May 2011 address to the Academy of Catholic Theology in Washington, DC, Weinandy, warned of a "crisis" in Catholic theology, precipitated by theologians who "often appear to possess little reverence for the mysteries of the faith as traditionally understood and presently professed within the church." The Secretariat for Doctrine had previously criticized a book on the Trinity by St. Joseph Sr. Elizabeth Johnson of Fordham University in New York, leading to a defense of Johnson by many theologians as well as Fordham faculty. Weinandy's address did not mention any theologian by name. "Theology may be the only academic pursuit where one can seemingly be considered a theologian without actually having to know the subject matter," he said. "It would appear at times that a theologian need not actually know God." Describing the theological crisis, Weinandy said: "Much of what passes for contemporary Catholic theology, often is not founded upon an assent of faith in the divine deposit of revelation as proclaimed in the sacred scriptures and developed within the living doctrinal and moral tradition of the church."

In October 2010, Weinandy participated in the Seventh Round of the Catholic-Reformed Dialogue concluded in Henryville, Indiana. That dialogue was jointly sponsored by the USCCB Committee on Ecumenical and Interreligious Affairs, the Christian Reformed Church in North America, the Presbyterian Church-USA, the Reformed Church in America, and the United Church of Christ.

He was the Warden of Greyfriars (1993–2004; Honorary Fellow 2004) and tutor and lecturer in history and doctrine in the Faculty of Theology. He was chairman of the Faculty of Theology from 1997 to 1999. He is a member of the Catholic Theological Society of America, the Fellowship of Catholic Scholars, the Catholic Theological Society of Great Britain, the North American Patristics Society and the Association Internationale D'Etudes Patristiques, as well as the Academy of Catholic Theology. Since 2005, he has been the Executive Director of the Secretariat for Doctrine and Pastoral Practices of the United States Conference of Catholic Bishops (USCCB), until he was replaced in early 2013. The Secretariat provides staff support for USCCB Committees on Doctrine, on Pastoral Practices, and on Science and Human Values, as well as for Ad Hoc Committees on Health Care Issues and the Review of Scripture Translations.

His major fields of specialty are history of Christology, especially patristic, medieval and contemporary, history of trinitarian theology, history of soteriology, and philosophical notions of God. He has held academic positions at Georgetown University, Mount St. Mary's University in Emmitsburg, Maryland, Franciscan University of Steubenville, and Loyola College, Baltimore. Weinandy served at the University of Oxford from 1991 to 2005.

Weinandy entered the Order of Friars Minor Capuchin in 1966, was solemnly professed in 1970, and was ordained to the priesthood in 1972. He earned a BA in philosophy at St. Fidelis College, Herman, Pennsylvania, in 1969, an MA in systematic theology at Washington Theological Union in 1972, and a doctorate in historical theology at King's College London in 1975. He lived in and was an active member of the Mother of God Community, Washington, for 14 years before leaving to teach at Oxford University.
