An angel, no matter their status (i.e., archangel, cherubim, etc.), cannot be the promised Jewish Messiah: from the line of Abraham, the seed of David (Matt. 1.1).
"After all, when did God EVER say to ANY of the angels: 'You are my Son. Today I have become your Father? Or, even, I will be his Father, and he will be my Son?" Heb. 1.5 CEB
"In addition to the Shema, and perhaps in some cases as a substitute for it, one finds that at the beginning of the Christian era the formula heis ho theos, was used to express the monotheistic faith of Judaism. The currency of this confession in the Jewish world of that time is clearly demonstrated by the widespread evidence. A variety of Jewish sources contains the form heis theos [which] was, in effect, apostasy from the Roman religion, for Rome, though granting religious freedom to its subject people, also expected the recognition and worship of its own deities. According to Roman national faith, the Jews, as well as the Christians, were [atheists, Dio Cassus 67.14; Josephus, Bel. 7.410-419; cp. Contra Apionem]."
