There are three aspects to reincarnation, and therefore salvation in one of the most commonly studied doctrines of the Christian faith. The three aspects are the history of the doctrine, its origin and the purposes of the doctrine.
HISTORICAL Parents of the doctrine
Before Christianity as we know it developed, people lived in harmony with the natural laws of the universe. There was no sin, no death, no judgment, no need for salvation, or even a need for an afterlife. When Christianity matured, the Church Fathers developed the doctrine of redemption.
It was first suggested to me in a dream in 1973, and the idea that reincarnation was a real possibility was thrust into my full consciousness. Of course, in my youth, such a concept was completely outside of my understanding. I referred to myself as being a ‘Priest in toward God.’ As Christianity spread, the idea of the old ideas and practices gently was accepted, such as the practice of baptism, references to the twelve tribes of Israel, and the giving out of earrings and fringes by high officials as a sign of sanctity.
Ichever way that baptism was explained to the multitudes, the origins of the Christian sacrament of baptism has been lost in the passage of time. That the original Apostles used water for the current practice is true. However, the symbolism of the sprinkled blood is not the important thing. What is important, in my opinion, is the knowing that, as believers in Christ, we offer, not just our blood, but our own lives; a sacrifice made by our Lord on our behalf. By accepting Christ as our Saviour, the Lord has accepted our Resurrected flesh as His own, and we become a living sacrifice. We are made partakers of that glorious resurrection to eternity. As such, the Christian is destined to live out the most glorious purpose of any human being: to live forever in the presence of his or her Creator.
Placing the believer into the historical baptism of the Holy Ghost and fire, the Apostles proclaimed to the world that the Godhead was now a living reality. The Trinity had appeared to human history, the Son had Emerged from the Father, and the Holy Ghost had Shed His Divine Influence throughout the world. The idea of an invisible Christ dwelling throughout the earth and each one of us, communing with the Father and the Son, was born in the second century.
The Baptismalm of the Holy Ghost is, itself, an expression of the Trinity, with the person of the Father, the Son and the Holy Spirit coming together in unity, in the natural world, as brothers and sisters, in the one Heavenly Father, with the only begotten Son. All Teachings originated in the Holy Bible, and are based upon the teachings of the Old and New Testaments. Although the ceremonies and rituals of Baptism may be regarded as historical, the main essence of the Faithendooly fits its ancient origins. The Baptism of the Holy Ghost is simplysoogical, logical, profound, and beautiful.
SOME IMPORTANT NOTES:
 1 Cor 15:7-8 faculty of unity, in the body of Christ, includes believers who are members of one body and have come to love one another. For, Christ died to take the Glory and share the same spiritual blessings. Therefore, the gifts of the Spirit may be enjoyed by members of one body. (Emphasis mine)
 2 Tim 2:1-5 Wherefore I remind you to stir up the gift of God which is in you through the laying on of hands, the gift of the Spirit, wherewith all men freely share the gift of God; [therefore] without spot redemption seems hid to them (correct anatomy : for they do not see as yet  the gift of God), but great power and signs and wonders shall be done by the Spirit of our God, as by the breath of the Almighty; And they that fear him shall be strong, having his countenance and his wonders shall go forth in their bodies. (Brackets mine)
 1 John 3:9 For many times, when they food and drink, they say, This is the way that I like (or the way I prefer) to drink in the Lord; and they have not known that the Lord thank him not. (I would have wordy rather than plain) For if they knew, they would sin against the Lord. ( brackets mine)
 Dr Haim Ginott’s commentary on 1 John 3:9, The Theology of the New Testament Divinity, p Says: “It is true that ‘the life’ is in the spirit, but the will or desire of the flesh is in the belly, and so they are powerless against the power of the Spirit and of God’s grace.”
