Co-President of the World Council of Churches
Wejryd studied at Uppsala University, where he received his Bachelor of Divinity degree in 1972. In the same year, he was ordained priest in Västerås. He has served as priest in Västerås, Munktorp and Arboga, and was vicar of the parish Munktorp-Odensvi from 1978 to 1985, and vicar of Arboga parish and rural dean of the deanery Köping-Arboga from 1985 to 1987. In the 1980s, he continued part-time doctoral studies, doing research on Nathan Söderblom's missionary work until 1987, when his new job left him no time to continue. From 1987 to 1995 he was director of Ersta diakonisällskap (a church-connected foundation in Stockholm running a small hospital, social care activities and a nursing college), before becoming Bishop of Växjö in 1995, and Archbishop of Uppsala in 2006.
Wejryd was the first Archbishop to be elected after the separation of the Church of Sweden from the state on January 1, 2000. This meant that the Government of Sweden had no role in his appointment. In the preliminary election on February 8, 2006, he received 33% of the votes among 14 candidates (of which only eight received any votes at all). In the first round of voting on March 15, six candidates remained, and Wejryd received a plurality of votes, 44.6%, but not an absolute majority, with Ragnar Persenius as runner-up at 30.8%. A second round of voting between Wejryd and Persenius was arranged on March 30, where Wejryd received 176 votes (58.1%) against 127 for Persenius.
Wejryd took up his office on September 2, 2006. He met with Pope Benedict XVI in March 2007. In June 2010, he officiated at the wedding of Crown Princess Victoria and Daniel Westling.
