That’s all well and good. The problem is despite the fact as you say “The bread and wine does not change…”, in that short video he clearly says, “you just ate the body of Christ. You are holding the blood of Christ”.
One of those positions isn’t true. Either it is the body and blood of Christ, or…the bread and wine are just bread and wine.
I can understand a faith based communion as you state it… but not at the same time as claiming that it is the body and blood of Christ.
It is Christ’s body and blood pneumatologically. As well known Pentecostal teacher Nathaniel Van Cleave once wrote:
We seek a deeper spiritual reality as a present moment [of] experience. We do not believe superstitiously that the bread and wine actually become the physical body and blood of Christ, nor do we believe that there is any virtue in the physical elements themselves apart from their power as figures to point us to the deeper reality which they typify. We do believe, however, that an act of faith in partaking of the elements results in the real operation of the Spirit in us to strengthen us in the inner man and to heal us in our physical bodies. We, furthermore, believe that the reality which the Lord’s Supper signifies is our “daily bread” of which we partake day by day.
Or as Cleveland, Ohio pastor D. W. Kerr wrote:
Faith can grasp mysteries that are unexplainable. Faith enters into a realm far beyond the sphere of understanding, and can extract the good and joy out of what soars high above our reasonings. We have no need to preach a doctrine of consubstantiation nor of transubstantiation; we just receive Jesus’ words and act on them. “Whoso eateth my flesh and drinketh my blood, hath everlasting life.”
Or as William A. Cox wrote:
It is not an empty service, it does not mean simply being served with a little bread and wine on the first Sunday of the month— it is a means of fellowship with God, through Jesus, by the Spirit, and we have a right to come to it expecting God to meet us. Indeed we have a right to expect to draw so near to God that whatever our need may be at that moment, whether spiritual or physical, He will supply it. . . . when we eat of the divine body of the Lord Jesus, the living Bread which came down from heaven. . . He quickens the spiritual man; He revives the physical; He heals our diseases, and gives us strength to live by. By eating Jesus, the Bread of life, we have life in our physical bodies. . . . if we eat the flesh of Jesus, and drink His blood, we shall live by Him. So when you want to be healed, just take a great big meal of Jesus.
They are symbols, but they are symbols that the Holy Spirit works through and through which the power of the Christ’s atonement is mediated to those who discern the Lord’s body in faith. So yes, from our perspective, it is proper for a believer to say that he is partaking of the body and blood of the Lord when he takes communion if he does so in faith.
