Last weekend it was that time again.

Joe Biden had himself driven to “his” Catholic Church St. Joseph on the Brandywine in his native Wilmington (state of Delaware) on Palm Sunday evening.

Biden is one of the most loyal visitors to the church in whose cemetery Biden's first wife, his parents and two deceased children are buried.

What visiting the golf course was for Donald Trump at the weekend, going to church is for Biden.

Joseph "Joe" Robinette Biden is an avowed Catholic - and only the second Catholic President of the United States. Does the denomination of the US president even play a role? And how much Catholicism is there in Joe Biden and his politics anyway?
