14. Concerning the signs of the Trinity.

D. In how many ways does Scripture indicate the Persons, or existences, of divinity? M. Similarly, in two, primarily and secondarily: primarily, as when we say 'Father, Son, Holy Spirit'; secondarily, through those <words>by which essence or operation or comparison to creatures is indicated. For even when I say, 'God,' which pertains to essence, and when I say, 'almighty,' which pertains to operation, and when I say, 'immutable,' which is said from comparison to creatures, although a first hearing perceives another thing, nevertheless I secondarily understand God, Father and Son and Holy Spirit, either together or singly.
