The Tetragrammaton (YHWH) isn't really a name – its a means of describing the indescribable. It literally means "to be, become, come to pass" and is usually translated as "I am" or "I will be." It comes from Exodus when God declares "I am that I AM," or "I will be that I WILL BE." In English we struggle with this concept. The word is more like "I am," "You are," "He/she/it is," "We are," and "They are," all rolled up into one convenient word. The German language as a better translation than English – the word "sein," with is roughly "be." This is usually taken to mean that when God identified Himself as YHWH, He was declaring that He was above any naming convention, that nothing could be likened unto Him, or that He is being/existence itself.
The Son, though, hypostatically joined to human nature, is not above naming conventions, for He adopted the name Yeshua, or Joshua, or the Greek "Jesus." To say that God's name is Jesus is not errant, but to say that the Father's or Spirit's name is Jesus is indeed errant.
