You should start with Christ. He had no earthly wife.
So? Marriage is not a sin — it was created and ordained by the Almighty.
Christ’s martial status was not actually mentioned in the Bible either. This is not to say that I believe He was married ... I don’t. I, like most everyone else, assume He was unmarried (mostly because I figure His wife would’ve been mentioned had she existed). But His unmarriedness, like that of any disciples other than Paul, was not pivotal enough to warrant a mention.
The question is not whether Christ was married. It is whether celibacy should be a mandate for priests — Peter’s apostleship seems to suggest it should not.
