Paul's letters were addressed to the "Holy Ones" who were still very much alive as sinful humans in their imperfect flesh. (Rom 1:7; 1 Cor 1:2; 2 Cor 1:1; Eph 1:1; Phil 1:1; Col 1:2)
Rom 1:7 (ESVST) 7 To
all those in Rome who are
loved by God and called to be saints: Grace to you and peace from God our Father and the Lord Jesus Christ.
1Co 1:2 (ESVST) 2 To the church of God that is in Corinth, to those sanctified in Christ Jesus,
called to be saints together with all those who in every place call upon the name of our Lord Jesus Christ, both their Lord and ours:
2Co 1:1 (ESVST) 1 Paul, an apostle of Christ Jesus by the will of God, and Timothy our brother, To the church of God that is at Corinth,
with all the saints who are in the whole of Achaia:
Gal 1:1-2 (ESVST) 1 Paul, an apostle — not from men nor through man, but through Jesus Christ and God the Father, who raised him from the dead — 2 and
all the brothers who are with me,
To the churches of Galatia:
Eph 1:1 (ESVST) 1 Paul, an apostle of Christ Jesus by the will of God, To
the saints who are in Ephesus, and are faithful in Christ Jesus:
Phi 1:1-2 (ESVST) 1 Paul and Timothy, servants of Christ Jesus, To
all the saints in Christ Jesus who are at Philippi, with the overseers and deacons: 2 Grace to you and peace from God our Father and the Lord Jesus Christ.
Col 1:1-2 (ESVST) 1 Paul, an apostle of Christ Jesus by the will of God, and Timothy our brother, 2 To
the saints and faithful brothers in Christ at Colossae: Grace to you and peace from God our Father.
1Th 1:1 (ESVST) 1 Paul, Silvanus, and Timothy, To the church of the Thessalonians in God the Father and the Lord Jesus Christ:
1Th 1:4 (ESVST) 4 For we know,
brothers loved by God, that he has chosen you,
So, please explain to me, how can there be only 144,000 brothers of Jesus? Was Paul writing to only 2 or maybe 3 saints and brothers in each of his letters?
