First, we must recognize that there is no law, canonical or Divine, that forbids usage of the Divine Name even in its most proper pronunciation outside of liturgical events. Thus, one can find many Bibles, devotionals, texts, and such which have the Divine Name printed or used in such a way that expects verbal expression. The Church, being the New Israel, tolerates this practice and really doesn’t speak one way or the other, but simply asserts that the custom of the substitutionary reverence of the Name be respected. Private devotion however is a different matter. Theologically speaking, one can justify quite easily a Christian’s ability (or even right, in some sense) to verbalize the Divine Name. We are literally sons and daughters of God; we know God through the intimacy of Jesus Christ; God dwells within us, and so on. Usage of the Divine Name also can provide an intimacy with God and a sense of deepened identity with the Old Covenant, which has been continued and fulfilled in the New.
Second, it is the clear that compromises can be made with the Divine Name so as to keep the usage close but imperfect out of respect for the Name. The pronunciation of the tetragrammaton is very precise and follows a form of Hebrew that is no longer spoken natively. Thus, one can easily “garble” the true pronunciations whilst keeping the general structure. Some examples include: “Yaveh,” “Iahveh,” “Yahvé,” “Yah,” “Jahveh,” “Jah,” “Iabe,” “Yao,” and so on. One can also use a device founded by our Jewish ancestors which inserts different vowels into the tetragrammaton creating new names (which are, by nature, titles) such as: “Jehovah,” “Yehowah,” “Yahoveh,” “Yiyeh,” “Jehoveh,” and more.
Third, we must recognize that the Name of God is found more fully in Christ than in the tetragrammaton. The name “Jesus” is derived from the Hebrew “Yehoshua” (meaning: “YHWH saves”). It was shortened in the mid to late Old Covenant to “Yeshua” which is the Hebrew/Aramaic form of Our Lord’s Name. Thus, anytime the Name of Jesus is mentioned, the Divine Name is included by the nature of the Hebraic formula as “Yeh,” “Yah,” and “Yoh” all form linguistically equivalent expressions of the Name: “Iahveh.” This truth reminds us that the Name of Jesus is far more exalted and worthy of reverence than even the Divine Name in the New Covenant. The Catechism of the Catholic Church explains:
CCC, 2666: But the one name that contains everything is the one that the Son of God received in his incarnation: JESUS. The divine name may not be spoken by human lips, but by assuming our humanity The Word of God hands it over to us and we can invoke it: “Jesus,” “YHWH saves.” The name “Jesus” contains all: God and man and the whole economy of creation and salvation. To pray “Jesus” is to invoke him and to call him within us. His name is the only one that contains the presence it signifies. Jesus is the Risen One, and whoever invokes the name of Jesus is welcoming the Son of God who loved him and who gave himself up for him.
So I would say that a Christian is free to use the Divine Name (preferrably in a compromised form) during his or her private devotions; especially if it is invoked in silence. Any utterance however
must be accompanied by all due reverence, honor, and sense of the sacred. Any usage of the Divine Name or titles and words related to it (God, Lord, etc.) which are used disrespectfully or even frivolously is a sin against the Second Commandment. That being said, I encourage instead an increased usage and sense of reverence be cultivated in the Name of “JESUS,” as the Catechism states above. In the Name “JESUS” we receive all that was and is and will be the power of the Divine Name, YHWH, and also the very Presence of Christ in our hearts. I personally pray with the usage: “Iahveh” to God, especially on important or momentous occassions, however I strive to follow the Catechism’s teaching and rely more on the Name of Christ than the Divine Name as it was used in the Old Covenant.
I submit everything I have said, written, or implied to the judgment and correction of Holy Mother Church; most especially the Holy Roman Church under whose care I have been placed by God. Anything here that contradicts the teaching of Holy Mother Church in any way is null, void, and downright incorrect and should be seen as such.
