As stated above, it’s just another name for Jesus. It doesn’t mean the same as Jesus, however. He has several other terms with which he is described in the bible.
Ex.
DAB
Luke 1:32-
He shall be great, and shall be called the Son of the most High; and the Lord God shall give unto him the throne of David his father; and he shall reign in the house of Jacob for ever.
Luke 1:35-
And the angel answering, said to her: The Holy Ghost shall come upon thee, and the power of the most High shall overshadow thee. And therefore also the Holy which shall be born of thee shall be called the Son of God.
Isaiah 7:14
Therefore the Lord himself shall give you a sign. Behold a virgin shall conceive, and bear a son, and his name shall be called Emmanuel
Isaiah 9:6-
For a CHILD IS BORN to us, and a son is given to us, and the government is upon his shoulder: and his name shall be called, Wonderful, Counsellor, God the Mighty, the Father of the world to come, the Prince of Peace.
The term, “shall be called,” or “shall be named” is used many times to mean that someone shall be considered, or known for. Jesus is considered the Prince of peace, the Son of God, etc., but that was not his given name when he was on Earth. It’s a descriptor.
