Early Christians have a testimony which should not be dismissed. Such might not be considered, so it would be appropriate to share what is yet found from very early Christian writers nearest to the time of Christ's resurrection and the start of the Christian church.
Here is an excerpt from Clement of Alexandria, Book 2, Chapter 1:
God has provided for His creature (man I mean) food and drink, for sustenance, not for pleasure; since the body derives no advantage from extravagance in viands. For, quite the contrary, those who use the most frugal fare are the strongest and the healthiest, and the noblest; as domestics are healthier and stronger than their masters, and husbandmen than the proprietors; and not only more robust, but wiser, as philosophers are wiser than rich men. For they have not buried the mind beneath food, nor deceived it with pleasures. But love (agape) is in truth celestial food, the banquet of reason. "It beareth all things, endureth all things, hopeth all things. Love never faileth." "Blessed is he who shall eat bread in the kingdom of God." But the hardest of all cases is for charity, which faileth not, to be cast from heaven above to the ground into the midst of sauces. And do you imagine that I am thinking of a supper that is to be done away with? "For if," it is said, "I bestow all my goods, and have not love, I am nothing." On this love alone depend the law and the Word; and if "thou shalt love the Lord thy God and thy neighbour," this is the celestial festival in the heavens. But the earthly is called a supper, as has been shown from Scripture. For the supper is made for love, but the supper is not love (agape); only a proof of mutual and reciprocal kindly feeling. "Let not, then, your good be evil spoken of; for the kingdom of God is not meat and drink," says the apostle, in order that the meal spoken of may not be conceived as ephemeral, "but righteousness, and peace, and joy in the Holy Ghost." He who eats of this meal, the best of all, shall possess the kingdom of God, fixing his regards here on the holy assembly of love, the heavenly Church. Love, then, is something pure and worthy of God, and its work is communication. "And the care of discipline is love," as Wisdom says; "and love is the keeping of the law." And these joys have an inspiration of love from the public nutriment, which accustoms to everlasting dainties. Love (agape), then, is not a supper. But let the entertainment depend on love. For it is said, "Let the children whom Thou hast loved, O Lord, learn that it is not the products of fruits that nourish man; but it is Thy word which preserves those who believe on Thee." "For the righteous shall not live by bread." But let our diet be light and digestible, and suitable for keeping awake, unmixed with diverse varieties. Nor is this a point which is beyond the sphere of discipline. For love is a good nurse for communication; having as its rich provision sufficiency, which, presiding over diet measured in due quantity, and treating the body in a healthful way, distributes something from its resources to those near us, But the diet which exceeds sufficiency injures a man, deteriorates his spirit, and renders his body prone to disease. Besides, those dainty tastes, which trouble themselves about rich dishes drive to practices of ill-repute, daintiness, gluttony, greed, voracity, insatiability. Appropriate designations of such people as so indulge are flies, weasels, flatterers, gladiators, and the monstrous tribes of parasites--the one class surrendering reason, the other friendship, and the other life, for the gratification of the belly; crawling on their bellies, beasts in human shape after the image of their father, the voracious beast. People first called the abandoned aswtous, and so appear to me to indicate their end, understanding them as those who are (aswsous) unsaved, excluding the S. For those that are absorbed in pots, and exquisitely prepared niceties of condiments, are they not plainly abject, earth-born, leading an ephemeral kind of life, as if they were not to live [hereafter]? Those the Holy Spirit, by Isaiah, denounces as wretched, depriving them tacitly of the name of love (agape), since their feasting was not in accordance with the word. "But they made mirth, killing calves, and sacrificing sheep, saying, Let us eat and drink, for to-morrow we die." And that He reckons such luxury to be sin, is shown by what He adds, "And your sin shall not be forgiven you till you die," --not conveying the idea that death, which deprives of sensation, is the forgiveness of sin, but meaning that death of salvation which is the recompense of sin. "Take no pleasure in abominable delicacies," says Wisdom. At this point, too, we have to advert to what are called things sacrificed to idols, in order to show how we are enjoined to abstain from them. Polluted and abominable those things seem to me, to the blood of which, fly "Souls from Erebus of inanimate corpses."
"For I would not that ye should have fellowship with demons," says the apostle; since the food of those who are saved and those who perish is separate. We must therefore abstain from these viands not for fear (because there is no power in them); but on account of our conscience, which is holy, and out of detestation of the demons to which they are dedicated, are we to loathe them; and further, on account of the instability of those who regard many things in a way that makes them prone to fall, "whose conscience, being weak, is defiled: for meat commendeth us not to God." "For it is not that which entereth in that defileth a man, but that which goeth out of his mouth." The natural use of food is then indifferent. "For neither if we eat are we the better," it is said, "nor if we eat not are we the worse." But it is inconsistent with reason, for those that have been made worthy to share divine and spiritual food, to partake of the tables of demons. "Have we not power to eat and to drink," says the apostle, "and to lead about wives"? But by keeping pleasures under command we prevent lusts. See, then, that this power of yours never "become a stumbling-block to the weak."
For it were not seemly that we, after the fashion of the rich man's son in the Gospel, should, as prodigals, abuse the Father's gifts; but we should use them, without undue attachment to them, as having command over ourselves. For we are enjoined to reign and rule over meats, not to be slaves to them. It is an admirable thing, therefore, to raise our eyes aloft to what is true, to depend on that divine food above, and to satiate ourselves with the exhaustless contemplation of that which truly exists, and so taste of the only sure and pure delight. For such is the agape, which, the food that comes from Christ shows that we ought to partake of. But totally irrational, futile, and not human is it for those that are of the earth, fattening themselves like cattle, to feed themselves up for death; looking downwards on the earth, and bending ever over tables; leading a life of gluttony; burying all the good of existence here in a life that by and by will end; courting voracity alone, in respect to which cooks are held in higher esteem than husbandmen. For we do not abolish social intercourse, but look with suspicion on the snares of custom, and regard them as a calamity. Wherefore daintiness is to be shunned, and we are to partake of few and necessary things. "And if one of the unbelievers call us to a feast, and we determine to go" (for it is a good thing not to mix with the dissolute), the apostle bids us "eat what is set before us, asking no questions for conscience sake." Similarly he has enjoined to purchase "what is sold in the shambles," without curious questioning?
We are not, then, to abstain wholly from various kinds of food, but only are not to be taken up about them. We are to partake of what is set before us, as becomes a Christian, out of respect to him who has invited us, by a harmless and moderate participation in the social meeting; regarding the sumptuousness of what is put on the table as a matter of indifference, despising the dainties, as after a little destined to perish. "Let him who eateth, not despise him who eateth not; and let him who eateth not, not judge him who eateth." And a little way on he explains the reason of the command, when he says, "He that eateth, eateth to the Lord, and giveth God thanks; and he that eateth not, to the Lord he eateth not, and giveth God thanks." So that the right food is thanksgiving. And he who gives thanks does not occupy his time in pleasures. And if we would persuade any of our fellow-guests to virtue, we are all the more on this account to abstain from those dainty dishes; and so exhibit ourselves as a bright pattern of virtue, such as we ourselves have in Christ. "For if any of such meats make a brother to stumble, I shall not eat it as long as the world lasts," says he, "that I may not make my brother stumble." I gain the man by a little self-restraint.
