Shelah (Toldos Adam Ben Dovid 73) Tzadikim will in the future called by G-d’s Name as it is said Everything that is called in My Name and for My Honor, I created it, even I made it. And those who adhere to it are called tzadik by His Name, because they bind and unite the Heavens with the Earth. And He said that they are made like the image of G-d, because G-d has creation, formation, and action in Him. Even the tzaddik below has included in him all of these, to establish the Divine Honor below.
Bava Basra (075b) Tzadikim will in time to come be called by the name of G-d; for it is said: Every one that is called by My name, and whom I have created for My glory. I have formed him, yea, I have made him. R. Samuel b. Nahmani said in the name of R. Johanan: Three were called by the name of G-d, and they are the following: The righteous, the Messiah and Jerusalem.
Bava Basra (075b) There will come a time when ‘Holy’ will be said before the righteous as it is said before G-d; for it is said: And it shall come to pass, that he that is left in Zion, and he that remains in Jerusalem, ‘shall be called Holy.
Marhasha (Bava Basra 75b) 3 things are called on the name of G-d. Seeing that it does not say with the name of G-d, but they were called on the name of G-d. This means the name of G-d will be associated with them - the Messiah, meaning the Lord's Messiah, Jerusalem, meaning the city of G-d, as well the tzaddik, meaning, a tzaddik to G-d. In other words all their actions are for the sake of Heaven. This as also true for Messiah that all his deeds are for the sake of Heaven. Also concerning Jerusalem the only ones allowed there will be those whose deeds are only for the sake of Heaven.
