Matthew 8:14

Or; In Peter's wife's mother is shown the sickly condition of infidelity, to which freedom of will is near akin, being united by the bonds as it were of wedlock. By the Lord's entrance into Peter's house, that is into the body, unbelief is cured, which was before sick of the fever of sin, and ministers in duties of righteousness to the Saviour.

But for what intent did He go into Peter's house? As it seems to me, to take food. This at least is declared when it is said, "She arose and ministered unto Him." For He used to visit His disciples (as Matthew likewise, when He had called him), so honoring them and making them more zealous. But do thou mark, I pray thee, herein also Peter's reverence towards Him. For though he had his wife's mother at home lying ill, and very sick of a fever, he drew Him not into his house, but waited first for the teaching to be finished, then for all the others to be healed; and then when He had come in, besought Him. Thus from the beginning was he instructed to prefer the things of all others to his own. Therefore neither doth he himself bring Him in, but He entered of His own accord (after the centurion had said, "I am not worthy that Thou shouldest come under my roof"): to show how much favor He bestowed on His disciple. And yet consider of what sort were the houses of these fishermen; but for all that, He disdained not to enter into their mean huts, teaching thee by all means to trample under foot human pride. And sometimes He heals by words only, sometimes He even stretches forth His hand, sometimes He doeth both these things, to bring into sight His way of healing. For it was not His will always to work miracles in the more surpassing manner: it being needful for Him to be concealed awhile, and especially as concerned His disciples; since they out of their great delight would have proclaimed everything. Having therefore touched her body, He not only quenched the fever, but also gave her back perfect health. Thus, the disease being an ordinary one, He displayed His power by the manner of healing; a thing which no physician's art could have wrought. For ye know that even after the departing of fevers, the patients yet need much time to return to their former health. But then all took place at once. And not in this case only, but also in that of the sea. For neither there did He quiet the winds only and the storm, but He also stayed at once the swelling of the waves; and this also was a strange thing. For even if the tempest should cease, the waves continue to swell for a long time. But with Christ it was not so, but all at once was ended: and so it befell this woman also. Wherefore also the evangelist, to declare this, said, "She arose and ministered unto Him;" which was a sign both of Christ's power, and of the disposition of the woman, which she showed towards Christ. And another thing together with these we may hence observe, that Christ grants the healing of some to the faith even of others. Since in this case too, others besought Him, as also in the instance of the centurion's servant. And this grant He makes, when there is no unbelief in him that is to be healed, but either through disease he cannot come unto Him, or through ignorance imagines nothing great of Him, or because of His immature age.

For naturally the greatest weakness follows fever, and the evils of sickness begin to be felt as the patient begins to recover; but that health which is given by the Lord's power is complete at once.

(De Cons. Ev. ii. 21.) When this miracle was done, that is, after what, or before what, Matthew has not said. For we need not understand that it took place just after that which it follows in the relation; he may be returning here to what he had omitted above. For Mark relates this after the cleansing of the leper, (Mark 1:30.) which should seem to follow the sermon on the mount, concerning which Mark is silent. Luke also follows the same order in relating this concerning Peter's mother-in-law as Mark; also inserting it before that long sermon which seems to be the same with Matthew's sermon on the mount. But what matters it in what order the events are told, whether something omitted before is brought in after, or what was done after is told earlier, so long as in the same story he does not contradict either another or himself? For as it is in no man's power to choose in what order he shall recollect the things he has once known, it is likely enough that each of the Evangelists thought himself obliged to relate all in that order in which it pleased God to bring to his memory the various events. Therefore when the order of time is not clear, it cannot import to us what order of relation any one of them may have followed.

Or by Peter's mother-in-law may be understood the Law, which according to the Apostle was made weak through the flesh, i. e. the carnal understanding. But when the Lord through the mystery of the Incarnation appeared visibly in the synagogue, and fulfilled the Law in action, and taught that it was to be understood spiritually; straightway it thus allied with the grace of the Gospel received such strength, that what had been the minister of death and punishment, became the minister of life and glory.
