The Anglican tradition is rich in symbolism. In fact you could get a lesson in theology just looking around the sanctuary of most Episcopal churches before the service. There are symbols in the stained glass windows, symbols on the altar linens, symbols on the vestments and altar frontals. There are symbols on the furniture, on various crosses, on statues and in Christian art. As John Bradner says in his book on the subject, a symbol is “intended to suggest meaning. It represents something below the surface. Like a sign it is a means of communication, a device to direct our thinking.“
In the month of June we celebrate Trinity Sunday (June 3rd), which is rich in symbolism. The Christian church understands God to have been revealed to us as three “persons” or forms: Father, Son, and Holy Spirit. Trinity Sunday honors this doctrine. Since we understand God to be one God and not three gods, the Trinity symbols emphasize this.
A common symbol for Trinity Sunday is the equilateral triangle. Others are the three-leaved clover (three leaves on one stem) the Fleur de Lis, the words Holy, Holy, Holy, three interwoven circles, three fishes in a triangle and other assorted groupings of three.
