3. “And this,” He adds, “is eternal life, that they may know Thee, the only true God, and Jesus Christ, whom Thou hast sent.” The proper order of the words is, “That they may know Thee and Jesus Christ, whom Thou hast sent, as the only true God.” Consequently, therefore, the Holy Spirit is also understood, because He is the Spirit of the Father and Son, as the substantial and consubstantial love of both. For the Father and Son are not two Gods, nor are the Father and Son and Holy Spirit three Gods; but the Trinity itself is the one only true God. And yet the Father is not the same as the Son, nor the Son the same as the Father, nor the Holy Spirit the same as the Father and the Son; for the Father and Son and Holy Spirit are three [persons], yet the Trinity itself is one God. If, then, the Son glorifies Thee in the same manner “as Thou hast given Him power over all flesh,” and hast so given, “that He should give eternal life to all that Thou hast given Him,” and “this is life eternal, that they may know Thee;” in this way, therefore, the Son glorifies Thee, that He makes Thee known to all whom Thou hast given Him. Accordingly, if the knowledge of God is eternal life, we are making the greater advances to life, in proportion as we are enlarging our growth in such a knowledge. And we shall not die in the life eternal; for then, when there shall be no death, the knowledge of God shall be perfected. Then will be effected the full effulgence of God, because then the completed glory, as expressed in Greek by δόξα. For from it we have the word δόξασον, that is used here, and which some Latins have interpreted by “clarifica” (make effulgent), and some by “glorifica” (glorify). But by the ancients, glory, from which men are styled glorious, is thus defined: Glory is the widely-spread fame of any one accompanied with praise. But if a man is praised when the fame regarding him is believed, how will God be praised when He Himself shall be seen? Hence it is said in Scripture, “Blessed are they that dwell in Thy house; they will be praising Thee for ever and ever.” There will God’s praise continue without end, where there shall be the full knowledge of God; and because the full knowledge, therefore also the complete effulgence or glorification.
