The Nicene Creed says God proceeds (verb) from God and God.
The noun spiration is the act of this proceeding.
Sort of like how the noun "hearing" is "the act of perceiving sounds" to describe the verb "hear".
The noun procession means "continuous motion forward".
So procession is the act of proceeding.
What are the differences between spiration and procession so that we could understand them as two distinct acts?
