Let these, therefore, when they keep to themselves the word of preaching, hear with terror the divine sentences against them, to the end that fear may expel fear from their hearts. Let them hear how he that would not lay out his talent lost it, with a sentence of condemnation added (Matth. xxv.24, &c.). Let them hear how Paul believed himself to be pure from the blood of his neighbours in this, that he spared not their vices which required to be smitten, saying, I take you to record this day, that I am pure from the blood of all men: for l have not shunned to declare unto you all the counsel of God (Acts xx.26, 27). Let them hear how John is admonished by the angelic voice, when it is said, Let him that heareth say, Come (Rev. xxii.17); in order doubtless that he into whose heart the internal voice has found its way may by crying aloud draw others whither he himself is carried; lest, even though called, he should find the doors shut, if he approaches Him that calls him empty. Let them hear how Esaias, because he had held his peace in the ministry of the word when illuminated by supernal light, blamed himself with a loud cry of penitence, saying Woe unto me that I have held my peace (Isai. vi.5). Let them hear how through Solomon the knowledge of preaching is promised to be multiplied to him who is not held back by the vice of torpor in that whereto he has already attained. For he says, The soul which blesseth shall be made fat; and he that inebriates shall be inebriated also himself (Prov. xi.25). For he that blesses outwardly by preaching receives the fatness of inward enlargement; and, while he ceases not to inebriate the minds of his hearers with the wine of eloquence, he becomes increasingly inebriated with the drought of a multiplied gift. Let them hear how David offered this in the way of gift to God, that he did not hide the grace of preaching which he had received, saying, Lo I will not refrain my lips, O Lord, thou knowest: I have not hid thy righteousness within my heart: I have declared thy truth and thy salvation (Ps. xxxix.10, 11  ). Let them hear what is said by the bridegroom in his colloquy with the bride; Thou that dwellest in the gardens, thy friends hearken: make me to hear thy voice (Cant. viii.13). For the Church dwelleth in the gardens, in that she keeps in a state of inward greenness the cultivated nurseries of virtues. And that her friends hearken to her voice is, that all the elect desire the word of her preaching; which voice also the bridegroom desires to hear, because he pants for her preaching through the souls of his elect. Let them hear how Moses, when he saw that God was angry with His people, and commanded swords to be taken for executing vengeance, declared those to be on God's side who should smite the crimes of the offenders without delay, saying, If any man is the Lord's, let him join himself to me; put every man his sword upon his thigh; go in and out from gate to gate through the midst of the camp, and slay every man his brother and friend and neighbour (Exod. xxxii.27). For to put sword upon thigh is to set earnestness in preaching before the pleasures of the flesh; so that, when any one is earnest to speak holy words, he must needs have a care to subdue illicit suggestions. But to go from gate to gate is to run to and fro with rebuke from vice to vice, even to every one by which death enters in unto the soul. And to pass through the midst of the camp is to live with such impartiality within the Church that one who reproves the sins of offenders turns aside to shew favour to none. Whence also it is rightly added, slay every man his brother and friend and neighbour. He in truth slays brother and friend and neighbour who, when he finds what is worthy of punishment, spares not even those whom he loves on the score of relationship from the sword of his rebuke. If, then, he is said to be God's who is stirred up by the zeal of divine love to smite vices, he surely denies himself to be God's who refuses to rebuke the life of the carnal to the utmost of his power.
But, on the other hand, those whom imperfection or age debars from the office of preaching, and yet precipitancy impells to it, are to be admonished lest, while rashly arrogating to themselves the burden of so great an office, they cut off from themselves the way of subsequent improvement; and, while seizing out of season what they are not equal to, they lose even what they might at some time in due season have fulfilled; and be shewn to have justly forfeited their knowledge because of their attempt to display it improperly. They are to be admonished to consider that young birds, if they try to fly before their wings are fully formed, are plunged low down from the place whence they fain would have risen on high. They are to be admonished to consider that, if on new buildings not yet compacted a weight of timbers be laid, there is built not a habitation, but a ruin. They are to be admonished to consider that, if women bring forth their conceived offspring before it is fully formed, they by no means fill houses, but tombs. For hence it is that the Truth Himself, Who could all at once have strengthened whom He would, in order to give an example to His followers that they should not presume to preach while imperfect, after He had fully instructed His disciples concerning the power of preaching, forthwith added, But tarry ye in the city until ye be endued with power from on high (Luke xxiv.49). For indeed we tarry together in the city, if we restrain ourselves within the enclosures of our souls from wandering abroad in speech; so that, when we are perfectly endued with divine power, we may then go out as it were from ourselves abroad, instructing others also. Hence through a certain wise man it is said, Young man, speak scarcely in thy cause; and if thou hast been twice asked, let thy answer have a beginning (Ecclus. xxxii.10). Hence it is that the same our Redeemer, though in heaven the Creator, and even a teacher of angels in the manifestation of His power, would not become a master of men upon earth before His thirtieth year, in order, to wit, that He might infuse into the precipitate the force of a most wholesome fear, in that even He Himself, Who could not slip, did not preach the grace of a perfect life until He was of perfect age. For it is written, When he was twelve years old, the child Jesus tarried behind in Jerusalem (Luke ii.42, 43). And a little afterwards it is further said of Him, when He was sought by His parents, They found him in the temple, sitting in the midst of the doctors, hearing them, and asking them questions (Ibid. v.46). It is therefore to be weighed with vigilant consideration that, when Jesus at twelve years of age is spoken of as sitting in the midst of the doctors, He is found, not teaching, but asking questions. By which example it is plainly shewn that none who is weak should venture to teach, if that child was willing to be taught by asking questions, who by the power of His divinity supplied the word of knowledge to His teachers themselves. But, when it is said by Paul to his disciple, These things command and teach: let no man despise thy adolescence (1 Tim. iv.11, 12), we must understand that in the language of Holy Writ youth is sometimes called adolescence  . Which thing is the sooner evident, if we adduce the words of Solomon, who says, Rejoice O young man in thy adolescence (Eccles. xi.9). For unless he meant the same by both words, he would not call him a young man whom he was admonishing in his adolescence.
 In English Bible, Psalm 40.p> The word adolescentia, used in the Vulgate, implies properly the age of immaturity, while growth is still going on. "Adolescentia, prima hominis ætas post pueritiam, et ante juventutem." Facciolati. St. Gregory's intention is to preclude the idea of Timothy having been called to "command and teach" at so immature an age as the word might seem to imply.
