The picture above shows us the "Seabury Window" in the Lady Chapel of Old Saint Paul's Scottish Episcopal Church in Edinburgh. Here's what their website says about Samuel Seabury:
Old Saint Paul’s has played a part in the foundation of the US Episcopal Church. The young American Samuel Seabury first worshipped at Saint Paul’s in 1752. In later years he was chosen to become the first Bishop of the United States and returned to Britain to be consecrated. As the prospective bishop of a fledgling republic, Seabury was faced with a choice: consecration in the Church of England required an oath of allegiance to the crown; however, this was not the case in the Scottish Episcopal Church.There is a wondeful essay by Bishop Seabury published right here entitled "AN EARNEST PERSUASIVE TO FREQUENT COMMUNION."
Remembering his days at Saint Paul’s, he returned to Scotland and was consecrated in 1784 in Aberdeen. His consecration is remembered on a plaque in Marischal College, Aberdeen, and in Edinburgh the Lady Chapel in Old Saint Paul’s is dedicated to Seabury’s memory.
Here is a very eloquent sample:
Consider these things, and let your own consciences determine, whether your neglect of the Holy Communion can be justified on any principles of Christianity or reason? Whenever you compare your conduct with Christ's command, sure I am, your own hearts must condemn you: Remember then, "God is greater than your heart, and knoweth all things." It is not so much with me, as with your God, you have this matter to settle; and did you attend to it, you would make no more excuses, but immediately prepare yourselves to become worthy guests at God's Table.
