The new Archbishop of Canterbury is to be formally enthroned after using a radio interview to back Church of England positions on homosexuality, which include opposition to same-sex marriage.
But Justin Welby told the BBC Thursday he is aware that many gays have enduring relationships of "stunning" quality that have "deeply challenged" his own views.
He also said in a Channel Five interview that there will be a female archbishop in the future despite failure to pass legislation backing the idea last year.
These controversial issues have dogged his predecessors.
Welby is to be formally enthroned at Canterbury Cathedral before statesmen and religious leaders. Welby is the 105th Archbishop of Canterbury and serves as head of the Church of England and spiritual leader of the world's Anglican Communion.
