Augustine of Hippo

(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.
