Other forms: messianically
Use the adjective messianic to describe something that has to do with a messiah, or savior, especially a religious one.
In Judaism, a messianic figure is predicted to appear in the future, and in Christianity that messianic role is filled by Jesus Christ. You can also describe a more earthbound savior as messianic — you might say that after a long, hot soccer match, your mom's arrival with a cooler full of water bottles seems almost messianic. The adjective comes from the noun messiah, which has an Aramic root, meshiha, or "the anointed of the Lord."
