Summary of text [comment] pages 50 and 51

[According to C.S. Peirce, existence falls into three categories. The categories are thirdness, secondness and firstness. These categories may be expressed as the realms of normal context3, actuality2 and possibility1.

Our witness of God should not be otherwise.

From the point of view of Peirce’s categories:

If a god is not “God the Three”, then this god cannot be “the One True God”.]
