Whether three fruits are fittingly assigned to the three parts of continence?

Objections

Objection 1 : It would seem that three fruits are unfittingly assigned to the three parts of continence: because twelve fruits of the Spirit are assigned, "charity, joy, peace," etc. (Gal. 5:22). Therefore seemingly we should reckon only three.
Objection 2 : Further, fruit denotes a special reward. Now the reward assigned to virgins, widows, and married persons is not a special reward, because all who are to be saved are comprised under one of these three, since no one is saved who lacks continence, and continence is adequately divided by these three. Therefore three fruits are unfittingly assigned to the three aforesaid.
Objection 3 : Further, just as widowhood surpasses conjugal continence, so does virginity surpass widowhood. But the excess of sixtyfold over thirtyfold is not as the excess of a hundredfold over sixtyfold; neither in arithmetical proportion, since sixty exceeds thirty by thirty, and a hundred exceeds sixty by forty; nor in geometrical proportion, since sixty is twice thirty and a hundred surpasses sixty as containing the whole and two-thirds thereof. Therefore the fruits are unfittingly adapted to the degrees of continence.
Objection 4 : Further, the statements contained in Holy Writ stand for all time: "Heaven and earth shall pass away, but My words shall not pass away" (Lk. 21:33): whereas human institutions are liable to change every day. Therefore human institutions are not to be taken as a criterion of the statements of Holy Writ: and it would seem in consequence that the explanation of these fruits given by Bede is unfitting. For he says (Expos. in Luc. iii, 8) that "the thirtyfold fruit is assigned to married persons, because in the signs drawn on the 'abacus' the number 30 is denoted by the thumb and index finger touching one another at the tips as though kissing one another: so that the number 30 denotes the embraces of married persons. The number 60 is denoted by the contact of the index finger above the middle joint of the thumb, so that the index finger by lying over the thumb and weighing on it, signifies the burden which widows have to bear in this world. When, however, in the course of enumeration we come to the number 100 we pass from the left to the right hand, so that the number 100 denotes virginity, which has a share in the angelic excellence; for the angels are on the right hand, i.e. in glory, while we are on the left on account of the imperfection of the present life."
