I found myself thinking on what Ben Witherington III wrote:

Paul is quite happy to speak about Christ assuming a variety of functions previously predicated only of Yahweh in the Old Testament. Though Paul did not articulate a full trinitarian theology, the raw stuff of trinitarian thinking surfaces again and again in his letters, especially in doxological texts, where Paul is thinking about whom he worships, or in prayer texts (cf. 1 Thess 1:2-5; 2 Cor 13:14). Paul had previously invoked blessing only in God’s name, but now God had three names by which the Lord could be called [italics mine]. (Ben Withernington, “Jesus as the Alpha and Omega of New Testament Thoughts,” in Contours of Christology in the New Testament, ed. Richard N. Longenecker [Grand Rapids: William B. Eerdmans, 2005], 44)

I found this fitting with today’s text from the lectionary:

In the presence of God, who gives life to all things, and of Christ Jesus, . . .  I charge you to keep the commandment without spot or blame until the manifestation of our Lord Jesus Christ, which he will bring about at the right time—he who is the blessed and only Sovereign, the King of kings and Lord of lords. It is he alone who has immortality and dwells in unapproachable light, whom no one has ever seen or can see; to him be honour and eternal dominion. Amen. (1 Tim 6:11-16 NRSV)
