Against the Arians: The substantiality of the Word proved from Scripture. If the One Origin be substantial, Its Word is substantial. Unless the Word and Son be a second Origin, or a work, or an attribute (and so God be compounded), or at the same time Father, or involve a second nature in God, He is from the Father's Essence and distinct from Him.
