Authorship. The authorship of these Epistles is one of the questions of NT. criticism upon which scholars are sharply divided. The objections urged against the Pauline authorship are of different kinds and varying degrees of weight, and may be briefly enumerated as follows: (a) Historical difficulties; (b) References to heresies; (c) Church organisation; (d) The description of St. Paul in the salutations; (e) Language and style.
(a) Historical Difficulties. It is impossible to find a place for these Epistles in the scheme of St. Paul's life, which is derived from the narrative in Acts and the references in the acknowledged Epistles. The journeys to which the Apostle makes reference are inconsistent with his movements as recorded in Acts. According to 1 Timothy 1:3, Timothy had been left at Ephesus while Paul proceeded to Macedonia; but in Acts 19:22; Acts 20:1; Timothy was sent from Ephesus to Macedonia in advance of St. Paul. In 1 Timothy 3:14 the Apostle intended to return to Timothy at Ephesus; but in Acts 20:4; Timothy was with him in Greece, and in Acts 20:14; Acts 20:17; St. Paul did not go to Ephesus, but sent for the Ephesian elders to meet him at Miletus. So in 2 Timothy 4:20 the reference to Trophimus cannot relate to the journey recorded in Acts 20:17 to Acts 21:8, for Trophimus accompanied the Apostle to Jerusalem (Acts 21:29). Again, the references in Titus 1:5; Titus 3:12, where St. Paul speaks of leaving Titus in Crete and asks him to meet him at Nicopolis, cannot be connected with the only occasion on which the Apostle visited Crete according to Acts (Acts 27:8), viz. when he was a prisoner en route for Rome, where Acts leaves him still under arrest.
These difficulties, however, are obviated when the tradition is accepted that St. Paul after his first imprisonment (Acts 28:30; Philippians 1:13) was set free in 62 or 63 a.d., and arrested again in 66 or 67. In the First Epistle of Clement of Rome to the Corinthians (about 97 a.d.) the writer speaks of St. Paul having 'gone to the extreme limit of the west.' This expression in a letter written at Rome seems to point to Spain. St. Paul had once hoped to visit that country (Romans 15:24); and in the 'Muratorian Fragment,' a document of date about 200 a.d., it is indicated that he had done so: a tradition which is mentioned later by Eusebius in the 4th cent., and Chrysostom in the 5th cent. If the genuineness of the Pastoral Epistles is established on other grounds, they give powerful testimony to St. Paul's activity during the period after Acts.
(b) References to Heresies. Many critics see in these Epistles, and especially in 1 Tim (1 Timothy 1:4; 1 Timothy 4:1; 1 Timothy 6:20), references to heresies which prevailed widely in the Church during the 2nd cent., and are classed under the name of Gnosticism. These heresies dealt with solutions of the problem of evil; they combined ideas from Jewish and heathen sources with Christian truth; they tended to represent Christ's earthly career and sufferings as only seeming, not real (Docetism); and they exalted knowledge (gnosis, whence the name) as a special privilege of the few, and superior to faith, the possession of the many.
The references to heresies in the Pastoral Epistles, however, are extremely vague and indefinite. There is no reference to Docetism, such as we find in 1 John (1 John 4:1), supposed to have been written at Ephesus before 100 a.d.; and the references to false doctrines in 1 Timothy 4:1; 1 Timothy 6:20 do not seem to require a 2nd-cent. date, or to conflict with the Pauline authorship any more than the references to heresies in Colossians 2:8; Colossians 2:18; Colossians 2:23 require that Epistle to be denied to St. Paul, and assigned to the 2nd cent. In the early Church, composed, as almost every congregation was, of elements diverse in race, education, and religion, it is not surprising to find the germs of false doctrine from the beginning, showing themselves sometimes in tendencies towards Jewish legalism (1 Timothy 1:7; Titus 1:14; Titus 3:9), as was the case among the Galatians at an earlier date; sometimes in philosophical speculations drawn from heathen sources (1 Timothy 4:7; 1 Timothy 6:20), as was previously the case among the Colossians. The heresies indicated in the Pastoral Epistles seem largely Jewish in origin. They are speculations about the Law (1 Timothy 1:7 cp. 2 Timothy 3:14), about genealogies (1 Timothy 1:14; Titus 3:9), about Jewish fables (Titus 1:14, and probably also 1 Timothy 1:4; 1 Timothy 4:7); and while the ascetic practices (1 Timothy 4:1) which some taught may have had some heathen elements, they are quite as likely to have been suggested by exaggerations of Jewish ceremonialism: see Romans 14:3; 1 Corinthians 8; 1 Corinthians 8; Colossians 2:16, and cp. 1 Timothy 4:4 with Acts 10:11.
(c) Church Organisation. It has been objected to St. Paul's authorship of these letters that the indications of Church organisation are such as point to a time later than that of St. Paul. Titus was appointed to 'ordain elders in every city' (2 Thessalonians 1:5) in Crete; and both he and Timothy were instructed as to the qualifications of 'the bishop' (Titus 1:7; 1 Timothy 3:1). Timothy was also given instructions regarding the deacons (1 Timothy 3:8). The organisation, however, does not seem when examined to be more developed than was necessary in the Churches almost from the beginning. Deacons had to be appointed at a very early date in the Church at Jerusalem-although the name was not then given them, the corresponding verb is used of their work—(Acts 6:4); and elders were appointed by St. Paul in every Church in Galatia on his first missionary journey (Acts 14:23); while at Ephesus, at the end of his third journey, they were evidently a recognised body (Acts 20:17) entrusted with the duties of overseeing and teaching the flock (Acts 20:28). Nor is the term 'the bishop' (1 Timothy 3:2; Titus 1:7) necessarily an indication of a post-apostolic date. For (1) it is largely held that the terms 'bishop' (episcopos) and 'elder' (presbuteros) are used synonymously in these Epistles, as they undoubtedly were at an earlier period (Acts 20:28 cp. Philippians 1:1); and (2) even if, as is also influentially maintained, 'the bishop' here means the principal minister of the Church, it would still be hazardous to pronounce the Epistles non-Pauline. Many good authorities trace back the beginnings of episcopacy to the apostolic age, and so it is by no means impossible that in an apostolic Epistle, written as late as 65-67 a.d., the term 'bishop' might occur in its later sense.
(d) Paul an Apostle. Another objection has been found in the fact that, in letters written to intimate friends and disciples, the writer should emphatically assert his apostleship. This trait, it is said, indicates that they were written by some one who was using the Apostle's name at a later time, as the Apostle himself did not mention his apostleship in letters written to those with whom he was on friendly terms, whether churches or individuals (Philippians 1:1; Philemon 1:1). But these Pastoral Epistles are not, properly speaking, private letters. They were probably intended to be read to the Churches: 'the author is writing with his eye on the community'; and the fact that heresy and incipient faction were to be guarded against, sufficiently explains the assertion of apostolic dignity.
(e) Language and Style. The difference in language and style which exists between these Epistles and the undoubted letters of the Apostle is felt by many to be a serious objection to their genuineness. It is impossible here to enter into details; but there are a great many words and phrases found in these books, which are absent from the other writings of St. Paul, and there are over a hundred and seventy words used which are not elsewhere present in NT. A number of these words are, of course, necessitated by the fact that new subjects are here discussed; but there are many which cannot be thus explained. And on this ground alone many refer the Epistles to a later writer, who, according to some, has incorporated in them (especially in 2 Tim) fragments of genuine lost letters of St. Paul.
The argument from language, however, is by no means conclusive. The differences from the other Pauline Epistles in language and style may be the consequence of lapse of time. As the Apostle became older and travelled over new ground, meeting with new experiences, and making new converts, it would not be wonderful if he gained a wider command of language, and adopted a different mode of expression, according to the necessities of the case. As Farrar points out ('St. Paul': Excursus 27), 'St. Paul was the main creator of theological language.' He 'had to find the correct and adequate expression for conceptions which as yet were extremely unfamiliar. Every year would add to the vocabulary, and the harvest of new expressions would always be most rich where truths already familiar were brought into collision with heresies altogether new.' It has recently been ascertained by an examination in detail of about two hundred words which are not elsewhere found in the NT. that none of them had its origin later than St. Paul, that nearly half of them are found in the Septuagint, that over fifty are found in classical writers and writers who flourished not later than St. Paul, and that almost all the rest can be explained as necessitated by new subjects, or formed from Pauline or biblical words, or as otherwise consistent with the apostolic authorship. The argument from language would be valid and conclusive had it been shown that a number of words used in these Epistles did not come into use until after St. Paul's day. The fact that none can be shown to be of later date, but that almost all can be proved to be contemporaneous with the Apostle, indicates that there is nothing in the language of the Pastorals to conflict with their claims to be St. Paul's. It may be added that even critics adverse to the Pauline authorship recognise in these letters the reflexions of thoughts and ideas characteristic of the Apostle. Many think they see incorporated in them reminiscences of the Apostle and private notes he had written to companions and friends (e.g. 2 Timothy 1:15; 2 Timothy 4:6; Titus 3:12), and describe them as Pauline, though not by the Apostle himself. Advocates of a 2nd-cent. date admit that a detailed comparison of the Pastorals with the letters of Clement of Rome, Ignatius, and Polycarp, exhibits the former as 'astonishingly superior': and acknowledge that the writer was saturated with the contents of the genuine Epistles of St. Paul. Apart, therefore, from the historical and internal difficulties which have been dealt with, the Epistles suggest the apostolic authorship, and bear the marks of St. Paul's personality; and as these difficulties seem all to be capable of explanation, we need have little hesitation in receiving them for what they profess to be.
