SK1 = Leviticus 20:21 states that a man marrying his brother’s widow is ‘unclean’ and will make the couple barren - Henry interpreted this as having no son as some translations used male pronouns
SK2 = The Pope had named Henry ‘Defender of the Faith’ in 1521 after he wrote an essay criticising Martin Luther - was clearly very religious and didn’t want to do anything that would upset God
CSK = Henry had many mistresses and even had an illegitimate son, the aforementioned Henry Fitzroy - if he could have sex outside of marriage his faith clearly wasn’t that important to him
