I find it shocking how many religious people are totally uneducated on the matter of marriage. Most of them believe that marriage was ordained by God and has been a part of the Christian faith since it's early days, but the modern version of marriage was not actually a part of the church until the Roman Catholic church in the 12th-13th centuries. Feel free to read on:
The Roman Catholic tradition of the twelfth and thirteenth centuries defined marriage as a sacrament ordained by God,[68] signifying the mystical marriage of Christ to his Church.[108]
"The matrimonial covenant, by which a man and a woman establish between themselves a partnership of the whole of life, is by its nature ordered toward the good of the spouses and the procreation and education of offspring; this covenant between baptized persons has been raised by Christ the Lord to the dignity of a sacrament."[109

That said, this certainly does not help Chik-Fil-A's reputation in my eyes.
Sorry but no. You only need to look at the writings of the early Christians to see that marriage was always seen as a sacred union. What the Catholic Church did was simply provide a formal definition of what marriage is. Feel free to read on:
"Flee wicked arts; but all the more discourse regarding them. Speak to my sisters, that they love in our Lord, and that their husbands be sufficient for them in the flesh and spirit. Then, again, charge my brethren in the name of our Lord Jesus Christ, that they love their wives, as our Lord His Church. If any man is able in power to continue in purity, to the honour of the flesh of our Lord, let him continue so without boasting; if he boasts, he is undone; if he become known apart from the bishop, he has destroyed himself. It is becoming, therefore, to men and women who marry, that they marry with the counsel of the bishop, that the marriage may be in our Lord, and not in lust. Let everything, therefore, be done for the honour of God." - Ignatius of Antioch, To Polycarp, 5 (A.D. 110).
"'What therefore God hath joined together, let not man put asunder.' See a teacher's wisdom. I mean, that being asked, Is it lawful? He did not at once say, It is not lawful, lest they should be disturbed and put in disorder, but before the decision by His argument He rendered this manifest, showing that it is itself too the commandment of His Father, and that not in opposition to Moses did He enjoin these things, but in full agreement with him. But mark Him arguing strongly not from the creation only, but also from His command. For He said not, that He made one man and one woman only, but that He also gave this command that the one man should be joined to the one woman. But if it had been His will that he should put this one away, and bring in another, when He had made one man, He would have formed many Women. But now both by the manner of the creation, and by the manner of lawgiving, He showed that one man must dwell with one woman continually, and never break off from her." - John Chrysostom, On Matthew 62:1 (A.D. 370).
"There is hardly anything more deadly than being married to one who is a stranger to the faith,where the passions of lust and dissension and the evils of sacrilege are inflamed. Since the marriage ceremony ought to be sanctified by the priestly veiling and blessing, how can that be called a marriage ceremony where there is no agreement in faith?" - Ambrose, To Vigilius, Letter 19:7 (A.D. 385).
