II Cor. 1:21-22 ... "He who establishes us with you in Christ and anointed us is God, who also sealed us and gave us the Spirit in our hearts as a pledge."
In these two verses Paul refers to the Holy Trinity as God (the Father), Christ (the Son), and the Spirit (the Holy Spirit). Although he never gives a detailed theological explanation of the Trinity, Paul frequently mentions Them and indicates some of their related functions. In this epistle (13:14) he states that God loves us, that He manifests this love to us as grace through Christ, and that by the Holy Spirit He has communion with us. In the above quoted text the apostle is content to show that the Holy Three work together in the purpose to save mankind from sin. In the original text Paul uses four participles, translated into English as verbs, to describe Their activity in the great work of human redemption.
First, Paul states that God establishes us in Christ. The word used here was a legal term from the business profession indicating a binding guarantee of a sale. That is, it obligated the seller to sell at the agreed price and the buyer to come up with the money to purchase it. The idea is that God has bound Himself to redeem man at the cost of Jesus' blood. When anyone wishes to repent and obey the gospel, God always follows through on His commitment to redeem that soul. He never reneges, but is always ready and willing to follow through on His guarantee. It says in I Tim. 2:4 that God "desires all men to be saved and to come to the knowledge of the truth." Jesus affirmed God's commitment to save the penitent when (Jno. 6:37) He declared, "All that the Father gives Me shall come to Me; and the one who comes to Me I will certainly not cast out."
Second, Paul says that we have been anointed by God. In the Mosaic period, when a priest or a king was commissioned to his office, he went through a ceremony of being anointed. Jesus, who was commissioned to be the eternal King and eternal High Priest, is often referred to as the Anointed. Both Messiah (Hebrew) and Christ (Greek) mean "anointed." The reference to Christians as being "anointed" is quite unusual; the only other application of this term to them in the New Testament is in I Jno. 2:20 and 27. When a person is baptized into Christ, he receives the "gift of the Holy Spirit," (Acts 2:38). This gift is his anointing to life and service in the Lord. Therefore, our being anointed is to Jesus, the Anointed One, as Christian is to Christ. God has honored us with a spiritual distinction resembling that of His Son's.
Third, Paul declares that God has sealed us. In ancient times, and to some extent at present, seals were employed to three purposes: to preserve, to designate ownership, and to authenticate the contents of something. Thus, a seal was put on a jar lid to preserve its quality; a seal was stamped on an item to identify who possessed it; and a seal was put on a document to signify the truth of its contents. The Holy Spirit is the Christian's seal, (Eph. 4:30), a seal which is placed upon us at baptism, (Acts 2:38). The Spirit seals us to preserve us as God's people, to proclaim we belong to God, and to authenticate us as sons of God.
Fourth, Paul states that God gives us the Spirit as an earnest. The word thus translated was another legal term from the business community. It indicated a deposit, or first installment, in the purchase of something. We still employ the word that way when we speak of "earnest money," a payment made on property to assure we will fully complete the purchase in time. God's gift of the Spirit to dwell within us is His "earnest payment" to declare He will fully claim our souls. We are assured in Rom. 8:11 that by the Holy Spirit, who has shared our Christian lives with us, we will be raised in the resurrection. In that great act God will complete the wonderful transaction of eternally redeeming our souls.
