Whether the ninth hour is suitably fixed for the faster's meal?

Objections

Objection 1 : It would seem that the ninth hour is not suitably fixed for the faster's meal. For the state of the New Law is more perfect than the state of the Old Law. Now in the Old Testament they fasted until evening, for it is written (Lev. 23:32): "It is a sabbath . . . you shall afflict your souls," and then the text continues: "From evening until evening you shall celebrate your sabbaths." Much more therefore under the New Testament should the fast be ordered until the evening.
Objection 2 : Further, the fast ordered by the Church is binding on all. But all are not able to know exactly the ninth hour. Therefore it seems that the fixing of the ninth hour should not form part of the commandment to fast.
Objection 3 : Further, fasting is an act of the virtue of abstinence, as stated above (Article [2]). Now the mean of moral virtue does not apply in the same way to all, since what is much for one is little for another, as stated in Ethic. ii, 6. Therefore the ninth hour should not be fixed for those who fast.
