On Wikipedia, there is an unattributed assertion (not in the citation) that when the former Anglican Bishop Andrew Burnham was received into the Roman Catholic Church, his wife was not received with him because she was Jewish. Mgr Burnham (as he now is) has subsequently been given Holy Orders in the Roman Catholic Church as part of the Personal Ordinariate of Our Lady of Walsingham and is a local priest in Oxfordshire and appears to be still married.
This possibly spurious assertion spurred a hypothetical question for me: can a Roman Catholic priest in ordinariate be married to someone who is not Catholic? I know that lay Catholics are allowed to marry non-Catholics, but is there a special rule for priests (within the already special rule for priests in the ordinariate) given they have consecrated their life to the Church ? Does it matter that the marriage may have (as would be in the case of the Burnhams) been conducted before the priest in question became a Catholic?
