Granville Sharp’s rule does not apply [to Proverbs 24:21 LXX]
Why not?
Basically, Granville Sharp's rule states that when you have two nouns, which are not proper names (such as Cephas, or Paul, or Timothy), which are describing a person.
In Titus and 2 Pe God and Savior are describing Jesus. What is God and king describing in Proverbs? It is missing.
Again you misunderstand the point G.B. Winer is making. He is saying that Titus 2:13 and 2 Peter 1:1 can be read in both ways, that God and Saviour can be understood as referring to one person or that God is referring to one and Saviour to another. Whoever reads those verses has an opinion as to the correct understanding. Winer is saying that considerations derived from Paul's system of doctrine lead him to believe that those verses are referring to both God and Jesus Christ. I concur.
Context rules note the question if Titus 2:13 is referring to one or two persons is answered by vs 14. = One person.
Let’s look at Paul’s doctrine.
Phil 2:6 who, being in the form of God, did not consider it robbery to be equal with God,
Notice equal translates from ‘isos’. Isos means ‘equal in quantity and quality. Paul’s doctrine supports the deity of Christ.
Equal = 2470 ἴσος [isos /ee•sos/] adj. Probably from 1492 (through the idea of seeming); TDNT 3:343; TDNTA 370; GK 2698; Eight occurrences; AV translates as “equal” four times, “agree together + 2258” twice, “as much” once, and “like” once. 1 equal, in quantity or quality. [Strongs]
I'm not quite sure what point you were making regarding the genitive of us, but perhaps you could comment on the significance of the difference in these two verses.
In response to
In Tit. ii. 13 considerations derived from Paul's system of doctrine lead me to believe that Saviour is not a second predicate, co-ordinate with God, - Christ being first called the great God and then Saviour. The article is omitted before Saviour, because this word is defined by the genitive of us, and because the apposition precedes the proper name : of the great God and of our Saviour Jesus Christ. Similarly in 2 P. i 1, where there is not even a pronoun with Savi
