● John 6:53 . . Amen, amen, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you do not have life within you.
When I was growing up a young Catholic boy back in the decade of the 1950s, the congregation was given the bread species at communion, but never the wine. In other words; in accordance with the principles of transubstantiation; we ate Jesus' flesh without his blood.
Well; Jesus' recipe for "life within you" consists of both his flesh and his blood. Therefore, none of my communions counted because they were half-baked, i.e. incomplete. I obtained no life from them: none of them; not a single one. I might just as well have used the host to make a peanut butter and jelly hor d'oeuvre for all the good it did me without the wine species.
It is not only necessary to imbibe the wine species in order to obtain life, but also to attain to Jesus' resurrection.
● John 6:53 . . Whoever eats my flesh and drinks my blood has eternal life, and I will raise him on the last day.
So then, according to the principles of transubstantiation, I was not only deprived eternal life due to being denied Jesus' blood; but my afterlife future was in grave peril too.
POSIT: It isn't necessary to partake of both species. According to 1Cor 11:27, Jesus' body and blood are contained in both; easily discerned by Paul's use of the word "or" in his teachings.
"So then, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord."
RESPONSE: Seeing as how Christ is the undisputed lord and master of Christianity; I do believe that whatever he says about his body and blood should trump however we might interpret Paul.
When Christ instituted the Lord's Supper, he had his men partake of both species: the wine and the bread. He did not give them the option to select between the two. No, he ordered them to partake of both species, and to do so while he supervised.
● Matt 26:26-28 . .While they were eating, Jesus took bread, said the blessing, broke it, and giving it to his disciples said: Take and eat; this is my body. Then he took a cup, gave thanks, and gave it to them, saying: Drink from it, all of you, for this is my blood of the covenant, which will be shed on behalf of many for the forgiveness of sins.
Matt 26:26-28 corroborates John 6:53-54 where Jesus testified: Amen, amen, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you do not have life within you. Whoever eats my flesh and drinks my blood has eternal life, and I will raise him on the last day.
1Cor 11:23-25 also corroborates John 6:53-54 by assigning each species its own special purpose: the bread for Christ's body, and the wine for his blood.
Therefore I must conclude that when Catholics partake of only one species of the Lord's Supper instead of both; they fail to obtain the life about which he spoke in John 6:53-54; ergo: they not only go away dead, but also in grave danger of missing out the better of the two resurrections spoken of in the book of Revelation.
They also fail to properly proclaim the Lord's death.
● 1Cor 11:26 . . For as often as you eat this bread and drink the cup, you proclaim the death of the Lord until he comes.
