Let me say right off the bat that I am still a Calvinist. But I no longer believe that Ephesians 1:4 supports the teaching that believers were chosen in Christ before the foundation of the world. It has become clear to me now that Paul was speaking only about the apostolic company. He says that "WE" (the apostles) were chosen in Christ before the foundation of the world, and that "YOU" (the Ephesians) were included in Christ when you heard the message of truth, and were marked in him when "YOU" believed.
It's interesting that the focus is on the 2 words ("we" and "you") for understanding Eph 1:4, when neither of them even occur in Eph 1:4. The key word on who God choses (elected) is "us".
So, let's examine the context:
1 Paul, an apostle of Christ Jesus by the will of God,
To God’s holy people in Christ Jesus:
2 Grace and peace to you from God our Father and the Lord Jesus Christ.
3 Praise be to the God and Father of our Lord Jesus Christ, who has blessed us in the heavenly realms with every spiritual blessing in Christ. 4 For he chose us in him before the creation of the world to be holy and blameless in his sight. In love predestined us for adoption to sonship through Jesus Christ, in accordance with his pleasure and will— 6 to the praise of his glorious grace, which he has freely given us in the One he loves. 7 In him we have redemption through his blood, the forgiveness of sins, in accordance with the riches of God’s grace 8 that he lavished on us. With all wisdom and understanding, 9 made known to us the mystery of his will according to his good pleasure, which he purposed in Christ, 10 to be put into effect when the times reach their fulfillment to bring unity to all things in heaven and on earth under Christ.
11 In him we were also chosen, having been predestined according to the plan of him who works out everything in conformity with the purpose of his will, 12 in order that we, who were the first to put our hope in Christ, might be for the praise of his glory.
13 And you also were included in Christ when you heard the message of truth, the gospel of your salvation. When you believed, you were marked in him with a seal, the promised Holy Spirit,
Verses 1-12 are about the apostles.
They were chosen in Christ before the foundation of the world, and were endowed with all spiritual blessings in Christ and were adopted as sons. We know that Paul was speaking about the apostles because he said that God had made known to them the mystery of his will that they might put into effect God's will. Believers did not put God's will into effect. The apostles put God's will into effect. We know too by the phrase "we who
FIRST trusted in Christ." It is the apostles who
FIRST trusted in Christ.
Verse 13 is about the Ephesians. They were not chosen in Christ before the foundation of the world as were the apostles. They were included in Christ "
when they heard the message of truth." They were marked in Christ
when they believed.
13 And you also were included in Christ when you heard the message of truth, the gospel of your salvation. When you believed, you were marked in him with a seal, the promised Holy Spirit,[/QUOTE]
None of this commentary changes the fact that Eph 1:4 isn't about either "we" or "you", but it's about "us".
So, who did Paul mean by "us"? Was he referring only to himself and his entourage, or referring to himself along with his audience to whom he was writing?
We know exactly who he was referring to by reading further into ch 1 at v.19 - and what is the surpassing greatness of His power
toward us who believe. These are in accordance with the working of the strength of His might.
So, the word "us" refers to those "who believe". That would include Paul, his entourage and his audience.
Therefore, Eph 1:4 tells us that God chooses (or elects) believers, to be holy and blameless. iow, that's what believers have been elected FOR.
Election has nothing to do with being chosen unilaterally for salvation. None of the 3 related Greek words for elect/election; whether noun (ekloge), verb (eklegomai) or adjective (eklektos), are used in Scripture for being chosen for salvation.
However, 2 Thess 2:13 does tell us the basis on which God does choose for salvation:
But we should always give thanks to God for you, brethren beloved by the Lord, because
God has chosen you from the beginning
for salvation through sanctification by the Spirit and faith in the truth.
iow, God choses to save those who have faith in the truth.
We see the same principle in 1 Cor 1:21 - For since in the wisdom of God the world through its wisdom did not come to know God,
God was well-pleased through the foolishness of the message preached
to save those who believe.
To say that God was pleased to save those who believe indicates who He was pleased to choose to save.
