Ambrose of Milan Patristic
A.D. 339–397
“For he who receives the followers of Christ, receives Christ; and he who receives the image of God, receives God; but because we cannot see the image of God, it has been made present to us by the incarnation of the Word, that the divine nature which is above us, may be reconciled to us.”
“For John loving much, and therefore much beloved, thinks that they should be excluded from the privilege who did not practise obedience.”

A.D. 376–444
“(non occ.) The devil lays plots of various kinds for them that love the best way of life. And if indeed by carnal allurements he can gain possession of a man’s heart, He sharpens his love of pleasure; but if a man has escaped these snares, he excites in him a desire of glory, and this passion for vain-glory had seized some one of His apostles. Hence it is said, Then there arose a reasoning among them, which of them should be the greatest. For to have such thoughts, belongs to him who desires to be superior to the rest; but I think it improbable that all the disciples gave way to this weakness; and therefore suppose that the Evangelist, not to seem to lay the charge to any individual, expresses himself indefinitely, saying, that there arose a reasoning among them.”

“Now He still more plainly conveys the meaning of the preceding words, saying, For he that is least among you all, the same shall be great; in which He speaks of the modest man who from honesty thinks nothing high of himself.”
“But we ought to consider not so much the worker of the miracles, as the grace which was in him, who, by the power of Christ, performed miracles. But what if there should be both those which be numbered together with the Apostles, and those who are crowned with the grace of Christ; there are many diversities in Christ’s gifts. But because the Saviour had given the Apostles power to cast out evil spirits, (Matt. 10:8.) they thought no one else but themselves alone was permitted to have this privilege granted to him, and therefore they come to enquire if it were lawful for others also to do this.”

“As if He said, On the side of you who love Christ, are all they who wish to follow those things which conduce to His glory, being crowned with His grace.”

Bede the Venerable Patristic
c. A.D. 672–735
“Therefore in heretics and false catholics, it becomes us to abhor, and forbid not the common sacraments in which they are with us, and not against us, but the divisions contrary to peace and truth, wherein they are against us as following not the Lord.”

c. 1055–1107
“Now it seems that this feeling was excited by the circumstance of their not being able to cure the demoniac. And while they were disputing thereupon, one said, It was not owing to my weakness, but another’s, that he could not be cured; and so thereby was kindled a strife among them, which was the greatest.”
“Marvel then at the power of Christ, how His grace works by means of the unworthy and those who are not His disciples: as also men are sanctified through the priests, although the priests be not holy.”

“And John answered and said, Master,.... The Syriac and Persic versions read, "our Master": we saw one casting out devils in thy name, and we forbad him; See Gill on Mar 9:38. Because he followeth not with us; the Syriac, Persic, and Ethiopic versions read, "because he followeth not thee with us"; did not join in company with them, and follow Christ along with them, and as they did.”

“And there entered a thought, &c. It is improbable that all the disciples had fallen into this fault: but the evangelist, that he might not point out any in particular as guilty of it, says indiscriminately, that this thought had entered among them. (St. Cyril in St. Thomas Aquinas)”

“STRIFE AMONG THE TWELVE WHO SHOULD BE GREATEST--JOHN REBUKED FOR EXCLUSIVENESS. (Luk 9:46-48) (See on Mat 18:1-5).”
