The ineffable name doctrine and Christianity

The "ineffable name" doctrine appears as early as the 150 AD/CE in the works of Justin Martyr, a Samaritan convert to Christianity. Justin made a special point about his many discussions with the Jews, discussions which apparently greatly influenced his own thinking in regard to the use of the name Yahweh:

And all the Jews even now teach that the nameless God spoke to Moses. (I Apol., 63)

Justin voices these opinions:

For God cannot be called by any proper name (Justin's Hortatory Address to the Greeks, 21)

For no one can utter the name of the ineffable God; and if any one dare to say that there is a name, he raves with a hopeless madness. (I Apol.,61)

Question, did Yahweh Himself rave with hopeless madness when He said "This is my name for ever, and this is my memorial unto all generations." in Exodus 3:15? Was the psalmist raving with hopeless madness when saying "I will take the cup of salvation, and call upon the name of Yahweh." in Psalm 116:17? This is among many false doctrines creeping into Christianity during in this era. We should return to the doctrine found in the scriptures.
