For the past few weeks one matter has been on my mind. Many people claim that Henry VII Tudor wanted his son Henry (later Henry VIII) to become a member of the Church. However Arthur Tudor's death meant that Henry became heir to the throne.
My questions is - if Arthur had lived, and Henry wanted to join the Church - how his career would have looked like? Could he had start from being a simple priest? I assume that Henry would have probably became Archbishop of Canterbury (the highest rank in Church) and Cardinal (appointed by Pope) and perhaps also Lord Chancellor. But as the king's brother (still assuming that Arthur had lived) would he had retained the title of Duke of York?
And also - if Katherine of Aragon bore a son by Arthur while Arthur was still alive, what title this boy would have had? Arthur was a Prince of Wales (usually first son has this title) and Henry was a Duke of York. Would that mean that this child as an heir presumptive also held the title of Prince of Wales?
Thank you for your time :-)
