The Great Commentary of Cornelius à Lapide
1 Corinthians 7:6
But I speak this by permission and not of commandment.
1. I permit the act of copulation by way of indulgence: I do not prescribe it. Nay, S. Augustine (Enchirid. c. 78) takes it: "I say this by way of pardon." The Greek word denotes forgiveness, and hence S. Augustine gathers that it is a venial sin to have sexual connection, not for the sake of children but for carnal pleasure, and to avoid the temptations of Satan; for pardon is given to what is sinful. So too indulgence is given in what concerns sin, or at all events a lesser good, as S. Thomas has rightly observed.
2. That there is no precept given here is also evident, because the Apostle permits married people to contain for a time, that they may give themselves to fasting and to prayer; therefore, if they agree to devote their whole life to fasting and to prayer, he permits them to contain themselves for life.
3. He says come together, and gives the reason, "that Satan tempt you not for your incontinency;" i.e., that there may be no danger of your falling into adultery, or other acts of impurity, because of your incontinency. Therefore, when the cause does not exist, viz., the danger of incontinency, as it does not exist in those who have sufficient high-mindedness to curb it and tame it, he permits them to be continent for life.
4. He says in ver. 7, "I would that all men were even as I myself," i.e., not chaste in some way or other, but altogether continent, unmarried, nay, virgin souls, even as I, who am unmarried. So Ambrose, Theodoret, Theophylact, Anselm, Chrysostom, Œcumenius and Epiphanius (Hæres. 78), S. Jerome (Ep. 22 ad Eustoch.)
5. In the early days of the Church many married persons, in obedience to this admonition of S. Paul, observed by mutual consent perpetual chastity, as Tertullian tells us (ad Uxor. lib. i. c. vi., and de Resurr. Carn. c. 8, and de Orland. Virg. c. 13). The same is said by the author of commentaries de Sing. Cleric., given by S. Cyprian.
Here are some examples of married persons, not merely of low estate, but people illustrious both for their birth and holiness and renown, who preserved their continency and chastity unimpaired in wedlock.
(1.) There are the Blessed Virgin and Joseph, who have raised the banner of chastity not only before virgins, but also before they married. (2.) We have the illustrious martyrs Cecilia and Valerian, who were of such merit that the body of S. Cecilia has been found by Clement VIII. in this age, after the lapse of so many centuries, undecayed and uninjured. (3.) There are SS. Julian and Basilissa, whose illustrious life is narrated by Surius. (4.) S. Pulcheria Augusta, sister of the Emperor Theodosius, made a vow to God of perpetual chastity, and on the death of Theodosius, married Marcian, stipulating that she should keep her vow, and raised him to the Imperial throne; and this vow was faithfully kept unbroken by both, as Cedrenus and others testify. (5.) We have the Emperor Henry II. and Cunegund, the latter of whom walked over hot iron to prove her chastity. (6.) There is the example of Boleslaus V., King of the Poles, who was called the Maid, and Cunegund, daughter of Belas, King if the Hungarians. (7.) King Conrad, son of the Emperor Henry IV., with Matilda his wife. (8.) Alphonse II. King of the Asturians, who by keeping himself from his wife gained the name of "the Chaste." (9.) Queen Richardis, who, though married to King Charles the Fat, retained her virginity. (10.) Pharaildis, niece of S. Amelberga and Pepin, was ever-virgin though married. (11.) Edward III. and Egitha were virgin spouses. (12.) Ethelreda, Queen of the East Angles, though twice married, remained a virgin. (13.) We have two married people of Arvernum, spoken of by Gregory of Tours (de Gloria Conf. c. xxxii.): "When the wife was dead, the husband raised his hands towards heaven, saying: 'I thank Thee, Maker of all things, that as Thou didst vouchsafe to intrust her to me, so I restore her to Thee undefiled by any conjugal delight.' But she smilingly said: 'Peace, peace, O man of God; it is snot necessary to publish our secret.' Shortly afterwards the husband died and was buried in another place; and, lo! in the morning the two tombs were found together, as is today: and therefore natives there are wont to speak of them as the Two Lovers, and to pay them the highest honour." Nowadays two examples of the same thing nay be found.
