“[W]e do put to confusion all those who, in whatever manner… assemble in unauthorized meetings; by indicating that tradition derived from the apostles, of the very great, the very ancient, and universally known Church founded and organized at Rome by the two most glorious apostles, Peter and Paul; as also the faith preached to men, which comes down to our time by means of the successions of the bishops. For it is a matter of necessity that every Church should agree with this Church, on account of its preeminent authority, that is, the faithful everywhere, inasmuch as the tradition has been preserved continuously by those who exist everywhere.
“The blessed apostles, then, having founded and built up the Church, committed into the hands of Linus the office of the episcopate… Eleutherius does now, in the twelfth place from the apostles, hold the inheritance of the episcopate. In this order, and by this succession, the ecclesiastical tradition from the apostles, and the preaching of the truth, have come down to us. And this is most abundant proof that there is one and the same vivifying faith, which has been preserved in the Church from the apostles until now, and handed down in truth.” (St. Irenaeus of Lyons, Against Heresies, III, iii, 2-3, ca. 180 AD)

Forming Consciences For Faithful Citizenship: A Call to Political Responsibility from the Catholic Bishops of the United States, with Introductory Note (Washington, DC: United States Conference of Catholic Bishops, 2011). Available at the United States Conference of Catholic Bishops.
But the things which the heathens sacrifice, they sacrifice to devils, and not to God. And I would not that you should be made partakers with devils: you cannot drink the chalice of the Lord, and the chalice of devils: You cannot be partakers of the table of the Lord, and of the table of devils…
All things are lawful for me, but all things are not expedient. All things are lawful for me, but all things do not edify…
If any of the unbelievers invite you, and you be willing to go; eat of any thing that is set before you, asking no question, for conscience sake. But if any man say: This hath been sacrificed to idols: do not eat of it for his sake that told it, and for conscience sake. Conscience, I say, not thy own, but the other’s…
Therefore, whether you eat or drink, or whatsoever else you do; do all things for the glory of God. Give no offence to the Jews, nor to the Gentiles, nor to the church of God: As I also please all men in all things, not seeking that which is profitable to myself, but to many; that they may be saved. (I Corinthians x, 20-21, 22, 27-29, 31-33)
