Assalam-Alaykum Brother,
The verse is 4:157
And [for] their saying, "Indeed, we have killed the Messiah, Jesus, the son of Mary, the messenger of Allah ." And they did not kill him, nor did they crucify him; but [another] was made to resemble him to them. And indeed, those who differ over it are in doubt about it. They have no knowledge of it except the following of assumption. And they did not kill him, for certain.
The Jews maybe were saying in a mocking way.
Your Question
Isa was the Messiah or Prophet?
In Islam Messiah doesn't mean God so Isa(PBUH) was a Prophet
or is it Allah addressing, Isa these titles to the believers?
Maybe
