The Eucharist is shown to be the true body and blood of Christ. I believe it is spiritual, since Jesus went [physically] back to the Father and he will return [physically] in the future to defeat the Antichrist.
and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age."
So Jesus is spiritually with us. In the same way He is spiritually present in the Eucharist.
It is the glorified Spirit-animated Flesh and Blood of the risen Christ [1 Corinthians 15]. Can you please be more specific as to which verse.
I don't believe that a distinction between
"physical" and "spiritual" is a very healthy way for a Christian to think. There are physical things, and there are non-physical things; some are Spiritual, some are carnal. The Holy Spirit is non-physical and Spiritual, but the risen body of the Resurrection is physical and also Spiritual. Satan and the demons are non-physical but carnal. An incarnate life lived to God is Spiritual. What do we mean when we say spiritual?
A life lived according to the Holy Spirit.
Something related to the Spirit of God working in the world.
In relation to your human spirit, which is currently incarnate because you are a material being.
Bodiless powers like Angels and Demons? I think we only really mean that when we're talking about the spiritual world/realm
, I.E. the existence of disembodied spirits. To quote a wise man here, I cannot recall whom: God the Father is Spirit, but he is not "a spirit".
Now, regarding 1:Corinthians 15, I was referring to the following verses:
"So also is the resurrection of the dead. It is sown a perishable body, it is raised an imperishable body; it is sown in dishonor, it is raised in glory; it is sown in weakness, it is raised in power; it is sown a natural body, it is raised a spiritual body. If there is a natural body, there is also a spiritual body. So also it is written, 'The first MAN, Adam, BECAME A LIVING SOUL.' The last Adam became a life-giving Spirit."
It is important to know that the English translations "natural body" and "spiritual body" are exceedingly poor. The word used for "natural" is "psyche", which means soul; it is a translation of the Hebrew word "nephesh", which is what God makes the first Adam when he is created ('the first Adam became a living soul'). Thus, this "soulish existence" is the manner in which a fallen human body exists; an existence which, as you and I know well, is quite physical.
"Spiritual body" could perhaps be better dynamically translated "Spirit-animated" or "Spiritualized" body. This body is not dis-incarnate or immaterial because of its relation to the spiritual realm. Rather, this body exists in a new mode of existence defined, sustained, and constituted from the Holy Spirit of God. It is this manner of existence which Christ gives to us when he gives us His Resurrected body as a prototype for our own, in Him. Therefore 1 Corinthians 15:44 could perhaps better be translated: "It is sown a Soulish Body, it is raised a Spiritualized Body."
If you would like to see a short related video, here is Anglican scholar N.T. Wright speaking briefly on the topic:http://www.youtube.com/watch?v=6jNaVgyqUD8
So we have seen that the Resurrected Body of Christ, which he ultimately shares with the totality of his Bride, is both Spiritualized and physical. So then, it is good to see also that this body, with its new mode of Spiritualized existence in the Coming Age of the Reign of Heaven which is already at hand, does not relate to reality in the same way that Soulish flesh does. Christ's spiritualized flesh can be broken, but not divided.
Remember, even before His Ascension, Christ stood somehow at the very tabernacle of heaven making atonement for the world, and one cannot say that he did this without his body, because he was Incarnate once for all, completely, for the Salvation of the World. Christ is not part incarnate; the Logos is not floating around somewhere with a little man Jesus occupying some of His time. This is a form of Docetism condemned by almost every major Christian denomination. Even the early Messianic Adoptionists didn't think some ghost Jesus was floating around apart from Jesus.
We believe that when we gather as Church to offer our bodies broken and our blood shed to God through Christ's, that we *really* enter into the heavenly altar and receive Christ's once-for-all atonement. Here we receive it in the only manner that an incarnate world could: bread to flesh, blood to body. This is the Christian faith as we understand it.
One question, having having received the Eucharist the first time, do you have eternal life right now?
Yes. We believe this is the quintessential work of belief through which all of our charity, suffering, faith and love are recapitulated in Christ. As he said: "I am the resurrection, and the life: he that believes in me, though he were dead, yet shall he live: And whosoever lives and believes in me shall never die." and "He who eats My flesh and drinks My blood has eternal life, and I will raise him up on the last day."
Hopefully this has been somehow helpful to you.
