Augustine of Hippo

(de Con. Ev. iii. 21) If Matthew and Mark had not mentioned by name Mary Magdalen, we should have thought that there were two parties, one of which stood far off, and the other near. But how must we account for the same Mary Magdalen and the other women standing afar off, as Matthew and Mark say, and being near the cross, as John says? By supposing that they were within such a distance as to be within sight of our Lord, and yet sufficiently far off to be out of the way of the crowd and Centurion, and soldiers who were immediately about Him. Or, we may suppose that after our Lord had commended His mother to the disciple, they retired to be out of the way of the crowd, and saw what took place afterwards at a distance: so that those Evangelists who do not mention them till after our Lord’s death, describe them as standing afar off. (Matthew and Mark.) That some women are mentioned by all alike, others not, makes no matter.
