Early life and ordination
Arborelius was born in Sorengo, Switzerland, of Swedish parents, and grew up in Lund in southern Sweden. He converted to Catholicism at the age of 20 and entered the Carmelites. He studied in Bruges and Rome and was ordained a priest in 1979.
When Arborelius succeeded Hubertus Brandenburg as Roman Catholic bishop of Stockholm (currently the only Roman Catholic diocese in Sweden and covering the entire country) in 1998, he became the first ethnically Swedish and second Scandinavian Catholic bishop in Sweden since the Reformation. (Most Catholic bishops in Scandinavia in the last century have been German or Dutch, although one, Knut Ansgar Nelson, was a Dane.)
Bishop Arborelius reportedly knew about SSPX bishop Richard Williamson's record of Holocaust denial before the latter's excommunication was lifted, something which was deemed controversial by a team of Swedish journalists.
