Congregation for Catholic Education (2003–2007) Miller was appointed as the secretary of the
Congregation for Catholic Education on November 23, 2003, as well as vice president of the Pontifical Work of Priestly Vocations. He was
consecrated bishop on January 12, 2004, at the Altar of the
Chair in
St. Peter's Basilica. During his term of office, Miller drafted and co-signed a document titled "
Instruction Concerning the Criteria for the Discernment of Vocations with Regard to Persons with Homosexual Tendencies in View of Their Admission to the Seminary and to Holy Orders". While the accompanying letter stressed that the directive "does not call into question the validity of the ordination" of men with "homosexual tendencies" who are priests, it did call for them "not to be appointed as rectors or educators in seminaries". However, Miller was reportedly "very uncomfortable" with the extreme reading of the instruction by
Tony Anatrella – who contended that gay men should be excluded from the priesthood altogether – on account of it "lacking balance". This was intended to help
Raymond Roussin, the
ordinary of the archdiocese at the time, who had depression in the preceding years. Miller established the
permanent diaconate in the archdiocese in 2011, with the first candidates of the program ordained four years later. He acted as principal consecrator at the episcopal ordination of
Stephen Jensen, held in
Prince George, British Columbia, on April 2, 2013. He also oversaw the construction of the new administrative headquarters of the Archdiocese of Vancouver, which opened in early 2015. Miller served as the principal consecrator at the episcopal ordination of
Joseph Phuong Nguyen at the
Sandman Centre in
Kamloops on August 25, 2016. In April of the following year, he was one of over 80 Catholic bishops to sign a "fraternal open letter" to the
German Bishops' Conference, expressing concern over the
Synodal Path process being undertaken in Germany at the time. ==Later life==
