Interesting but aren't Lutherans and Catholics great enemies of old?
Martin Luther started out trying to reform the church.
The Sunday church I go to uses white wine instead of red because the RCC said it had to be red. Luther verified there was no Biblical command for this, so some Lutherans use white wine,
still protesting the abuses, Pope, etc. of the RCC. The Reformation was a protest, which is where the term Protestant comes from. Hence, Protestant churches and Protestants, which includes essentially all the Western denominations and churches that left (directly or indirectly via those that left directky) the RCC. Churches, which serve both wine and grape juice in individual cups, usually use different colors to help Communicants differentiate between the two. For those on some medications, or who are recovering substance abusers, this is critical.
Orthodox and some Lutherans, who cross ourselves, do so in reverse direction to the RCC. Another form of protest. The propaganda perpetuated by RCC is that the Orthodox cross themselves the other way because they're East of Jerusalem. If this were the case, then Orthodox in the West would cross themselves the same way as Catholics do, but they don't. The Orthodox were the original Protestants, as they split/left from the RCC in 1054 (The Great Schism). Although most Orthodox say the RCC split from the Eastern church via heterodoxy, etc. and they're the original church. The filioque was the straw that broke the camel's back, and not the sole cause of the Orthodox leaving.
FWIW, most Lutheran churches do use red wine for the symbolism of the blood of Jesus, and most Lutherans and other liturgical Protestants (Episcopalian, Anglican, Presbyterian, Methodist, etc.), who cross themselves, cross themselves the same way as Catholics do. It's a symbolic act/tradition that's slowly going away as churches become less liturgical and more informal.
