From these 2 paragraphs of yours, you are believing that the Body of Christ has become the House of Israel and Judah of Hebrews 8:8?
You are ignoring the fact that on the Day of Pentecost Peter addressed the crowd as "
all the house of Israel" in Acts 2:36, and on that day about 3,000 Israelites accepted the New Covenant promised in Jeremiah 31:31-34, and Matthew 26:28.
The Gentiles were not grafted into the Church until several years later.
Act 2:14 But Peter, standing up with the eleven, raised his voice and said to them, "
Men of Judea and all who dwell in Jerusalem, let this be known to you, and heed my words.
Act 2:22 "
Men of Israel, hear these words: Jesus of Nazareth, a Man attested by God to you by miracles, wonders, and signs which God did through Him in your midst, as you yourselves also know—
Act 2:36 "Therefore
let all the house of Israel know assuredly that God has made this Jesus, whom you crucified, both Lord and Christ."
Act 2:37 Now when they heard this, they were cut to the heart, and said to Peter and the rest of the apostles, "Men and brethren, what shall we do?"
Act 2:38 Then Peter said to them, "Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins; and you shall receive the gift of the Holy Spirit.
Act 2:39 For the promise is to you and to your children, and to all who are afar off, as many as the Lord our God will call."
Act 2:40 And with many other words he testified and exhorted them, saying, "Be saved from this perverse generation."
Act 2:41 Then those who gladly received his word were baptized;
and that day about three thousand souls were added to them.
