In answer to your question, it is indeed profitable for everyone participating in the Mystery of the Sacrament of the Body and Blood of Christ, that they also know the Mystery of the Name of God.
You will recall when we were listening to Jesus pray to the Father at that Meal of his Last Supper that he said, “I have made your Name known to them, and I will make it known”.
So, the Name of God is this: “I AM”.
This Name is not limited to any certain language – you do not need to speak Hebrew and say, “AHYH”, nor Greek, “EGO EIMI”, nor Latin, “EGO SUM”.
But the Name of God is given in your native language. For those understanding in English, “I AM”.
Yes, it is true that people say that the Name of God in the Bible is written as “YHWH”, and in English is usually rendered with “LORD” because the Hebrew vowel markings were added to signify the pronouncing of “Adonai” rather than “YaHWeH”. “YHWH” itself it translated to English as “HE WHO IS”, a third person description of God, which can be used at a distance to talk about someone even if they are not present.
This use of YHWH and ADONAI pronunciation came about because of an event at Mount Sinai:
You may remember how, at the sight of the flashing lightning and the sound of the thunder and trumpets, with the Mountain smoking, there was tremendous fear, a mass fear of being near God, and a desire not to come near to Him for fear of death. [Exodus 20:18-21]
From that point on the people of God never came near him, but only His Priests or Prophets or Kings. From that point on the people only heard a descriptive word for God (“HE WHO IS” or “LORD”) and not his real name (“I AM”). This is why the word “YHWH” (YaHWeH, or “HE WHO IS”) was written in all the Hebrew Scriptures instead of “AHYH” (“I AM”), and even further fear with the Scribes, when the pronunciation was changed to say “Adonai” (“LORD”) by later generations who mistook “YHWH” for God’s Name. YHWH is like a “rubric”, allowing people to talk about God without actually being face to face.
When God’s Name is spoken, He is immediately present and immediately near. God does not come close at the sound of “YaHWeH” nor “Adonai” nor “LORD” nor “HE WHO IS”. But at his Name, “I AM” he is fully right here and right now. This is why Moses’ face was shining after his every encounter with God – he knew God by Name. But it would not be until the coming of Jesus that his Name would be made plain to all.
I encourage you to begin using God’s Name in your prayers with Him; begin saying his name when meditating on the Scriptures. For example, with a Psalm you would no longer read, “O LORD, how many are my foes!…” but you will invoke His Name as David did – David called God, “I AM”, even though it is copied in Scripture as “YHWH”, “LORD”, “HE WHO IS”, and this was to protect people afraid to approach near to God. David drew near to God, and now you, also.
So, invoke the Name of God as David did, and invoke his presence by speaking his Name:
O ‘I AM’, how many are my foes!
Many are rising against me;
many are saying of me,
there is no help for him in God.
But thou, O ‘I AM’, art a shield about me,
my glory, and the lifter of my head.
I cry aloud to ‘I AM’,
and he answers me from his holy hill.
I lie down and sleep;
I wake again, for ‘I AM’ sustains me.
I am not afraid of ten thousands of people
who have set themselves against me round about.
Arise, O ‘I AM’!
Deliver me, O my God!
For thou dost smite all my enemies on the cheek,
thou dost break the teeth of the wicked.
Deliverance belongs to ‘I AM’;
thy blessing be upon thy people!
[By the way, the English translation of “Jesus”, “Yeshua” is “I AM DELIVERING”, or “I AM SAVING”]
And again he declares later:
O ‘I AM’, our Lord,
how majestic is thy name in all the earth!
Any time you come across the word “LORD” in the Old Testament, begin finding God present by reading “I AM” instead. Even in the New Testament, in all the books written in Greek, when you see the word “Lord” referring to God, you can usually read, “I AM”; for instance, if there is a reference to “the Angel of the Lord” in the New Testament, it is perfectly correct to know this being as “The Angel of ‘I AM'”, or Mary, upon hearing from the Angel, “Hail, Full of Grace, ‘I AM’ is with you,” she finally replied, “Behold, I am the handmaid of ‘I AM’; let it be done to me according to your word.” Interesting, isn’t it, that Mary’s ‘being’ is as certain as the being ‘I AM’… There is no ‘becoming’ for this God, neither for his servants. When you are a servant, you are complete, you ARE.
When you think to be independent, you must make your being, meaning that “you are-not-yet”, and this is the beginning of “self-justification”, “self-righteousness”, trying to convince your “self” that you ARE when you are-not.
A servant has being in virtue of his master, vocational being, at the “vocation” of his master naming him “My servant”. When the master is ‘I AM’, there is full being, life, in his servant.
His servant “follows”, alive, doing his master’s Works.
