“In many respects, this trinity agrees with the Christian trinity: indeed I am nor aware that there are many points of disagreement. The interpretant is evidently the Divine Logos or word; and if our former guess that a Reference to an interpretant is Paternity be right, this would also be the Son of God. The ground, being that partaking of which is requisite to any communication with the Symbol, corresponds in its function to the Holy Spirit.”
(C.S. Peirce, Lowell Lecture XI, 1866, 503, The Essential C.S. Peirce)
