There is an unsearchableness in this mystery of the Godhead, in the mystery of God becoming Man; in the mystery of the Mediator his taking on these offices , to exercise them in our nature; and in speaking or thinking of them, there is a necessity to silence that which our curiosity would propose, for satisfactionabout them; as, namely ., how there are or can be three Persons in the Godhead , and yet but one God. How one of these persons can be man? and how it is , that by Him we have access to God the Father , Son , and Holy Ghost? There is silence required in the how of these things.
