Thus it is simply the emblem of the Papacy displayed on a red field. It is here represented with a gold cord instead of the usual red, so as to contrast with the red of the shield.
Symbolism
The crossed keys of gold and silver symbolise the keys of the kingdom of heaven promised to Saint Peter, with authority to bind and loose ().
The triple crown (the tiara) represents "the three powers of the Supreme Pontiff: Sacred Orders, Jurisdiction and Magisterium",[1] in other words: his functions as "supreme priest", "supreme pastor" and "supreme teacher".
