After rereading my post, I may owe the other posters an apology, or at least a clarification. I don't drink because I don't like it.
Nothing at all wrong with personal choice. I decided that it didn't fit the lifestyle I wanted. Plus for me it was always a social thing, we never had alcohol in the house.
To further clarify my clarification (there's probably some kind of clarified wine joke in there, but it would be best to ignore it), my apology wasn't about my choice to not drink, but rather about the possibility my post came across as though I was saying that drinking is immoral. That wasn't my intent.
To clarify what I was trying to say. To be outside of prayer itself is to be separated from God, so any activity which distracts from prayer is in itself "sin". The degree of distraction is important as to how long it takes one to get back to God, but to be distracted is to be separated regardless of how far one is from prayer.
Strangely enough the drinking of wine when used as "remembrance" fits into the realm of prayer. Because it leads to prayer. Most notably prayer of the heart region. Thoughts can only lead to God, but can't enter the recognisable presence of God. For this one must enter prayer of the heart which is beyond the mind and unobstructed by things of the world. Entering into ones heart is where you find God.
