Beginning in Luke 1, we read about Zacharias, father of John the Baptist (I'm using quite a few surrounding verses for context):
Luke 1:12-15: "Zacharias was troubled when he saw the angel, and fear gripped him. 13But the angel said to him, 'Do not be afraid, Zacharias, for your petition has been heard, and your wife Elizabeth will bear you a son, and you will give him the name John. 14You will have joy and gladness, and many will rejoice at his birth. 15For he will be great in the sight of the Lord; and he will drink no wine or liquor, and he will be filled with the Holy Spirit while yet in his mother’s womb.'"
A bit later in the same chapter of the Book:
Luke 1:59-66: "59And it happened that on the eighth day they came to circumcise the child, and they were going to call him Zacharias, after his father. 60But his mother answered and said, 'No indeed; but he shall be called John.' 61And they said to her, 'There is no one among your relatives who is called by that name.' 62And they made signs to his father, as to what he wanted him called. 63And he asked for a tablet and wrote as follows, 'His name is John.'"
Was there some symbolic reason that it was necessary to name the child "John"? Since no one in this family was named similarly, is there something of significance to the name "John" and the role he would play as "THE VOICE OF ONE CRYING IN THE WILDERNESS" (Lk. 3:4)?
