AmericanFlags.com features a wide variety of Papal flags, otherwise known as vatican flags or catholic flags in several sizes, styles and materials.
The Papal flag was adopted on June 7, 1929, the year when Pope Pius XI made the treaty with Italy, setting up a new independent state governed by the Popes. The square flag is vertically divided into two halves, the half closer to the flagpole is yellow, the other is white. The Vatican City coat of arms can be found in the white half. The coat of arms consists of: the papal tiara (as used under the pontificate of Pius XI); the two keys which represent the keys to Heaven (according to the Gospel of Matthew 16:19) given by Jesus Christ to St. Peter; and a red cord connecting the keys. The gold key in the Papal flag represents spiritual power, while the silver key represents worldly power.
