I have just received an interesting email with a question on the oldest titles for Jesus:
I would like your views on Mark 5:7 and Luke 1:32. In both of these quotes, Jesus is called Son of The Most High.

[2] Ibid. 685: "The canonical version of the majority text reads: Ἰησοῦ υἱὲ τοῦ θεοῦ τοῦ ὑψίστου. The manuscript readings, however, are important: The name Ἰησοῦ is absent in P75 D and in two Old Latin manuscripts(d e); τοῦ θεοῦ is also absent in D and in a series of other manuscripts. On the other hand, τοῦ ὑψίστου is attested almost throughout and absent only in aeth. This attestation situation clearly suggests that the address may have originally read υἱὲ τοῦ ὑψίστο υ, if D and the Old Latin manuscripts still exhibited traces of the pre-canonical text. Tertillian's attestation does not quote but only summarize this passage. Nevertheless, it reveals that his copy of *Ev read Ἰησοῦ υἱὲ τοῦ θεοῦ gelesen hat. [4] The trustworthiness of Tertullian's attestation is illustrated by his rhetorical question / as whose God's son did the demon witness Jesus? Again, Tertullian focuses on the uniformity of God's image, which was disputed by the Marcionites.
[4] Tert. 4,20,5: dei filium Iesum legio testata est.
