He is the senior communications adviser to the Vatican's Secretariat of State (and former correspondent for Fox News Channel). Burke writes about the Vatican on his Twitter account, as part of his daily routine. On March 26 he published two Twitter posts (see HERE and HERE) with images of Francis' Easter greeting card. Interestingly, the card includes the original papal coat of arms chosen by Francis, containing a five-pointed yellow star – inspired by his coat of arms as a former Cardinal. Symbols matter, in a church with more than 2,000 years of history and traditions – thus the papal coat of arms is considered the Pope's calling card.
