This description of the Trinity is not new, it popped into my head quick enough when thinking about Sunday’s services!!  I did however find this wonderful sermon on the subject, recklessly googling the line I came up with the Very Revd Alan Jones, a Londoner and Dean of Grace Cathedral – San Francisco his sermon is here

I shall unashamedly (quoting of course) have to borrow a little of that for Sunday as I explain the Rublev Icon of the Trinity.
