The Archbishop's Coat of Arms
Starting at the bottom, the motto is fac me pacis tuæ, instrumentum, Latin for “Make me an instrument of Thy peace,” part of a prayer written by an anonymous French soldier
probably in 1912 during the First World War (not by St. Francis of Assisi as some insist).
The hat and tassles at the top tell us he is an archbishop. In this case, Abp. Wynn is the Regionary Bishop for the Southern Province USA.
The shield is the Swedish flag, identifying his bloodline.
In the shield is an ouroboros
, an ancient symbol that shows a mythical dragon eating its own tail. In heraldry, the ouroboros can be seen as a symbol of eternity but also of self-purification.
The person on the shield thrusts a cross towards heaven, while pointing to the earth with his other hand (partly obscured). It is from a fairly well-known drawing made by Pamela Colman Smith
in 1909. It is a symbolic reference that clergy help connect that which is above to that which is below. The wise clergy know it is not the person doing the activity, and it certainly isn't the clergy's own grace. Abp. Wynn, never claiming wisdom, put this image on his Coat of Arms as a reminder that the work isn't being done for Wynn's benefit.
Behind the shield is a Patriarchial Cross
hinting at the Cross of Lorraine (the original cross of the Knights Templar).
