Hey Holy Rosary family, today is Flag Day, so what better time to reflect upon the significance of Vatican City’s flag, also known as the flag of the Holy See? YELLOW AND WHITE: The yellow (or gold) symbolizesheavenly power, while white (or silver) symbolizes earthly authority. PAPAL TIARA: A sign of the Pope’s sovereignty; the tiara depicted was worn by Pope Pius XI. TWO KEYS: Representing the Keys to the Kingdom given to St. Peter by Christ; again, gold symbolizes spiritual authority, while the silver key indicates temporal power. RED CORD: A cord connects the two keys, showing how they are linked, and both are possessed by the successor to Peter.
