Body of Christ begins: At Jesus resurrection, He is the firstfruit of the resurrection (1 Cor 15:20-23) & the Head of the Body (Col 1:18, Eph 1:22).
Shortly after Jesus resurrection, graves were opened (Matt 27:52 -53). Many bodies of OT saints which slept arose/were resurrcted & went into Jerusalem being seen by many. The 144 k (Rev 14:1-4) Also [I'm guessing] OT leadership Noah, Abraham, Moses, Elijah, David (Rev 4:10) & maybe everyone that was in Abraham's bosom.
Any of the above resurrected would-be parts of the Body of Christ. The NT body begins at the (Acts 2) Pentecost, with the outpouring of Christ's eternally indwelling Holy Spirit. Every post Pentecost NT believer receives Christ's Holy Spirit baptism.
The Holy Spirit is the earnest/seal (2 Cor 1:22, 5:5, Eph 1:13-14, 4:30). Earnest means deposit/down payment/seal. It's Christ's ever faithful promise of final redemption/resurrection into His presents FOREVER!

(d) ownership and security, together with destination, Revelation 7:3-Revelation 7:5 (as with the noun in Revelation 7:2; See A); the same three indications are conveyed in Ephesians 1:13, in the metaphor of the "sealing" of believers by the gift of the Holy Spirit, upon believing (i.e., at the time of their regeneration, not after a lapse of time in their spiritual life, "having also believed," not as AV, "after that ye believed;" the aorist participle marks the definiteness and completeness of the act of faith); the idea of destination is stressed by the phrase "the Holy Spirit of promise" (See also Ephesians 1:14); so Ephesians 4:30, "ye were sealed unto the day of redemption;" so in 2 Corinthians 1:22, where the Middle Voice intimates the special interest of the Sealer in His act;
