[2] From 1987 to 1989 Morerod was engaged in pastoral ministry, first as a deacon and then as vice-parish priest at the parish of St. Paul in Geneva.

From 2008 to 2011, he was also academic director of the Rome program for Catholic Studies students at the University of St. Thomas in St. Paul, MN.

In April 2009 he was appointed Secretary General of the International Theological Commission and Consultant of the Congregation for the Doctrine of the Faith.

A disciple of Charles Cardinal Journet, he has written several theological articles in the review Nova et Vetera, reflecting on the doctrinal and philosophical aspects of ecumenism.

On 3 November 2011 Pope Benedict XVI named Morerod Bishop of Lausanne, Geneva and Fribourg.

[7] However, it was also acknowledged that the number of reported cases of abuse involving Catholic priests and monks have been increasing over the past few years and that the payment of financial compensation which Morerod and his Diocese distributed for victims of abuse totaled CHF675,000 ($718,000) in 2018 - up from CHF425,000 in the previous year - according to figures released by the Vatican News.
