22. Now let us establish by evidence what we have said. The first point in the discussion is that all things serve. Now it is clear that all things serve, since it is written: “All things serve Thee.” Ps. cxix. [cxviii.] 91. This the Spirit said through the prophet. He did not say, We serve, but, “serve Thee,” that you might believe that He Himself is excepted from serving. So, then, since all things serve, and the Spirit does not serve, the Holy Spirit is certainly not included amongst all things.
