There are many verses like this that you are denying are referring to 2 Beings but are clear in context.
For instance, 1 Peter 1:2 says ‘God the Father’ in obedience to Christ. And 2 Peter 1:2 refers to knowledge of God AND of Jesus, our Lord.
It’s desperate to suppose God refers to anyone other than the Father when it is stated by these monotheists over and over again as 1 Peter 1:17 does. Implied is the absurd assertion that unless Scripture uses ‘the Father’ in invoking the word God, it must be referring to the son, by default.
It is far more consistent to go with the explicit ‘God the Father’ - which every epistle invokes - is being referred to when God alone is the text.
Since ‘God the Son’ is not stated once, it is the most extreme form of exegesis to suppose the word ‘God’ could be referring to any God but the one true God who is the Father of Jesus. Again, as explicitly stated in Ephesians 1:3 and other places.
Try sticking to the context and Greek construction of the verse in 2 Peter 1:1.
2 Peter 1:1
τοῦ θεοῦ ἡμῶν καὶ σωτῆρος Ἰησοῦ Χριστοῦ
2 Peter 1:11
τοῦ κυρίου ἡμῶν καὶ σωτῆρος Ἰησοῦ Χριστοῦ
2 Peter 1:1
our God and Savior, Jesus Christ
2 Peter 1:11
our Lord and Savior Jesus Christ
We have a second person possessive pronoun "Our" modifying two different improper nouns (God and Savior) joined by "and" (Kia) to identify a proper noun (Jesus) [Granville/Sharp's]. Therefore, by basic grammar, we are identifying Jesus as God and Savior. We don't even have to know the Greek to see that Jesus is being called both God and Savior/ Lord and Savior in Peters 2nd Epistle. 2 Peter 2:20 and 2 Peter 3:18 also have the same Greek construction as 1:1 and 1:11.
But for those interested in the Greek here is the comparison of 1:1 and 1:11.
τοῦ is the same.
ἡμῶν is the same.
καὶ is the same.
Σωτῆρος is the same.
Ἰησοῦ is the same.
Χριστοῦ· is the same.
And all in the same order.
The only difference is the noun "
Θεοῦ" in v.1, while "
Κυρίου" is in v.11.
So if he wants to deny that Jesus is "God" ("theou") in v.1, then he has to deny that Jesus is "Lord" ("kuriou") in v.11. Otherwise he's being inconsistent and dishonest with the text. To say otherwise is proof positive one has an agenda when reading scripture and using eisegesis rather than exegesis of the biblical text in question.
Peter refers to Christ as our God and Saviour- Lord and Saviour just the same as Paul in Titus 2:13 and it’s the same Greek construction in Titus 2:13 as it is in 2 Peter 1:1 and 1:11.
It’s time for you to wake up to that fact. It’s impossible for you to read it any other way because of your doctrine.
And the One who is coming / appearing in the NT is always the Son and NEVER the Father.
This is a trinitarian slam dunk !

7 That the trial of your faith, being much more precious than of gold that perisheth, though it be tried with fire, might be found unto praise and honour and glory at

Case closed for the Unitarian camp !
This is where Unitarians really fail badly because they are so consumed with disproving the Deity of Christ that they fail with a well rounded theology which would benefit them greatly . You see how all biblical doctrines fit together seamlessly and especially in this case prove beyond all doubt that the one and only Person Paul was referring to in Titus 2:13 as God was Jesus and not the Father for He is never once in Scripture referred to as the One who is Coming/ Appearing .
hope this helps !!!
