Continuing in the Church of St. Andrew and St. Mary in Grantchester, England, we come to this stained glass window (which appears fairly frequently in the television series Grantchester):
At the very peak we see one of the namesakes of the church, St. Andrew bearing his saltire cross in front of him.
In a row across the window a little way below St. Andrew we find the symbols of the Four Evangelists.
The authors of the four Gospels -- Matthew, Mark, Luke and John -- are known as the Evangelists. They are often represented (as they are here; please click on the image above to see a larger version of this photograph to see the details) with their attributes: the Angel or "divine man" for Saint Matthew, the Lion for Saint Mark, the Ox for Saint Luke (we have seen his symbol before in Antwerp, Belgium in a display of the arms of the Guild of St. Luke), and the Eagle for Saint John.
So, not heraldry, exactly, but certainly "heraldry-adjacent" (and here on shield shapes, no less!) as the symbols are standing in for the authors themselves, just as a coat of arms might.
