Give me just one verse where Paul uses the phrase "Bride of Christ."
Principles, not proof texts. Your negation of Johannine teaching also begs the question. John's visions included after the Second Coming of Christ with the Church (Jew and Gentile). The 7 churches in Rev. 2; 3 were after Paul's death and included Gentile churches.
"In the NT, the bride imagery is used often of the church and her relationship to Christ. The bride belongs to Christ, who is the bridegroom (Jn. 3:29). In Revelation, the church, as the bride of the Lamb, has prepared herself for marriage by performing righteous deeds (Rev. 19:7,8). In Rev. 21, the great wedding is portrayed with the church prepared for her bridegroom (21:2, 9). Finally, the bride and the Spirit issue an invitation to come (22:17). PAUL used the metaphor of the bride to indicate his feelings toward the churches he had founded. In 2 Cor. 11:2, Paul wrote that he had betrothed the Cor. church to Christ. He wanted to present the church as a pure bride to Christ. The Cor. were in danger of committing adultery. The imagery of the bride was used by various biblical writers, but they appear to have a single purpose. The bridal imagery is used to indicate the great love which God has for His people. For these writers, no image could express better this love than the ideal between a bridegroom and bride." Holman Bible Dictionary
Israel and the Church are both the people of God. The bride metaphor can be used by both, so proof texting Israel passages or resorting to extreme dispensationalism is not helpful.
Ephesians 5:22 ff. is also Pauline imagery comparing marriage relationships with the relationship of Christ to His church (bridegroom/bride)....5:32 "I am talking about Christ and the church..." (two become one)
Look up all the verses in OT/NT that use the word 'bride' before you are dogmatic.
"Body of Christ" is not the only NT metaphor for the Church (building, etc.).

(the bride imagery is more about the church triumphant in the future?)
