Eastern and Western Churches have different practices regard many things including the Eucharist. There are procedures that are followed for the proper purification of altar linens. Lots of info on line. White wine makes it easier to perform with good results.
Where in Scripture does it state that only "RED" wine is acceptable? That sounds a little legalistic; kind of like a protestants that practice believers baptism stating one can only be baptised but full immersion; sprinkling won't do... yet they deny baptism as a salvaic means of grace.
What about Bread? We do know that our Lord was celebrating the Passover in the upper room; we also know that only unleavened bread would be used at that meal. This is the also, as you know, the practice of most "western" Christians. Yet the orthodox use leavened bread; yet we western Christians not only accept the validity of the Eucharist in Eastern Churches, but don't take issue with the use of leavened bread.
Likewise, like Baptism, the mode of reception is only important regarding themings being done respectfully and in good order.
What really matters most is summed up in Luther's Small Catechism and regarding our discussion here, please see the highlighted portion below:
Part VI
Sacrament of the Altar
As the head of the family should teach it in a simple way to his household.
01 What is the Sacrament of the Altar?
02 Answer: It is the true body and blood of our Lord Jesus Christ, under the bread and wine, for us Christians to eat and to drink, instituted by Christ Himself.
03 Where is this written?
04 Answer: The holy Evangelists, Matthew, Mark, Luke, and St. Paul, write thus:
Our Lord Jesus Christ, the same night in which He was betrayed, took bread: and when He had given thanks, He brake it, and gave it to His disciples, and said, Take, eat; this is My body, which is given for you. This do in remembrance of Me.
After the same manner also He took the cup, when He had supped, gave thanks, and gave it to them, saying, Take, drink ye all of it. This cup is the new testament in My blood, which is shed for you for the remission of sins. This do ye, as oft as ye drink it, in remembrance of Me.
05 What is the benefit of such eating and drinking?
06 Answer: That is shown us in these words: Given, and shed for you, for the remission of sins; namely, that in the Sacrament forgiveness of sins, life, and salvation are given us through these words. For where there is forgiveness of sins, there is also life and salvation.
07 How can bodily eating and drinking do such great things?
08 Answer: It is not the eating and drinking, indeed, that does them, but the words which stand here, namely: Given, and shed for you, for the remission of sins. Which words are, beside the bodily eating and drinking, as the chief thing in the Sacrament; and he that believes these words has what they say and express, namely, the forgiveness of sins
.
09 Who, then, receives such Sacrament worthily?
10 Answer: Fasting and bodily preparation is, indeed, a fine outward training; but he is truly worthy and well prepared who has faith in these words: Given, and shed for you, for the remission of sins.
But he that does not believe these words, or doubts, is unworthy and unfit; for the words For you require altogether believing hearts.
