What does your faith say about abstemiousness, if anything. Do you try to apply it?
I try, I fail, I need more discipline, Lord have mercy. It is considered a sin to be a glutton and to be a drunkard, moderation in these things is incumbent on all and even fasting at times and not drinking at times is required. Gluttony is connected to lust and sloth and many to get rid of those vices will get rid of their gluttony first. Here are some statements from our Fathers on the matter:
"
It is just as shameful for lovers of the flesh and the belly to search out spiritual things as it is for a harlot to discourse on chastity." — St. Isaac the Syrian
"
A clear rule for self-control handed down by the Fathers is this: stop eating while still hungry and do not continue until you are satisfied." — St. John Cassian
"
According to St. Gregory the Sinaite there are three degrees in eating: temperance, sufficiency, and satiety. Temperance is when someone wants to eat some more food but abstains, rising from the table still somewhat hungry. Sufficiency is when someone eats what is needed and sufficient for normal nourishment. Satiety is when someone eats more than enough and is more than satisfied. Now if you cannot keep the first two degrees and you proceed to the third, then, at least, do not become a glutton, remembering the words of the Lord: 'Woe unto you that are full now, for you shall hunger' (Lk. 6:25). Remember also that rich man who ate in this present life sumptuously every day, but who was deprived of the desired bosom of Abraham in the next life, simply because of this sumptuous eating." — St. Nicodemos
And also Tertullian: "
Lust without voracity would certainly be considered a monstrous phenomenon; since these two are so united and concrete, that, had there been any possibility of disjoining them, the pudenda would not have been affixed to the belly itself rather than elsewhere. Look at the body: the region (of these members) is one and the same. In short, the order of the vices is proportionate to the arrangement of the members. First, the belly; and then immediately the materials of all other species of lasciviousness are laid subordinately to daintiness: through love of eating, love of impurity finds passage."
The ancient practice of the Church (from the Apostles) is recorded in the Didache, to fast on Wednesday and Friday (Wednesday for the betrayal of the Lord and Friday for His death): "
fast on the fourth day and the Preparation (Friday)." The Apostles also connect, which I just noticed in writing this and it truly is genius, fasting with loving our enemies recording the saying: "
bless those who curse you, and pray for your enemies, and fast for those who persecute you. For what reward is there, if you love those who love you?"
The Apostles also practiced beyond fasting, see this account of St. Matthew (the one who wrote the Gospel of St. Matthew) and the discipline he kept in eating always: "
happiness is found in the practice of virtue. Accordingly, the apostle Matthew partook of seeds, and nuts, and vegetables, without flesh." This refusal to eat meat is called abstinence, some practice it for some days each week or in periods of the year, others practice it always and such is virtuous.
To become drunk is to deprive yourself of reason deliberately and so is considered a grave sin, many swear off drinking for similar reasons entirely.
In short: we say a lot about it, there is a minimum to be kept and there are great heights to achieve by God's grace.
