The seven most authentic letters of St Paul are the most reliable sources for what the early Jesus-movement felt and thought. They are pretty close in time, 30s and 40s and 50s. The canonical gospels are much later writings, 70s and later, motivated by ideology and hierarchical organization of christians.
That can humiliate us a little when we talk about “the teaching of Christ”.
Peter
Careful here. You are stating your opinions as facts.
There are several issues with what you wrote above.
The biggest issue is that you state that the Gospels are motivated by ideology and hierarchical organization of Christians. This is clearly your own opinion and one that is not shared by the Church. The Church teaches that the entire Bible canon is inspired by the Holy Spirit and is all true and self consistent. Your statement has an agenda that is not in line with that way of thinking.
Secondly, you should not separate out Paul from the rest of the New Testament authors in the way that you did. Why is Paul’s view more authentic than John’s or James or Jude or In fact Peter’s, the first Pope. How did you come to this conclusion?
Third, you state as fact that the Gospels were written in the 70s or later. This is simply a theory. There is a credible alternative theory that places the Gospel of St. Matthew before 40AD, which would place it earlier than any of St. Paul’s writing. This is the commentary from the Catholic Encyclopedia on the subject:
Date and place of composition
Ancient ecclesiastical writers are at variance as to the date of the composition of the First Gospel. Eusebius (in his Chronicle), Theophylact, and Euthymius Zigabenus are of opinion that the Gospel of Matthew was written eight years, and Nicephorus Callistus fifteen years, after Christ’s Ascension–i.e. about A.D. 38-45. According to Eusebius, Matthew wrote his Gospel in Hebrew when he left Palestine. Now, following a certain tradition (admittedly not too reliable), the Apostles separated twelve years after the Ascension, hence the Gospel would have been written about the year 40-42, but following Eusebius (Church History III.5.2), it is possible to fix the definitive departure of the Apostles about the year 60, in which event the writing of the Gospel would have taken place about the year 60-68. St Irenæus is somewhat more exact concerning the date of the First Gospel, as he says: “Matthew produced his Gospel when Peter and Paul were evangelizing and founding the Church of Rome, consequently about the years 64-67.” However, this text presents difficulties of interpretation which render its meaning uncertain and prevent us from deducing any positive conclusion.
In our day opinion is rather divided. Catholic critics, in general, favour the years 40-45, although some (e.g. Patrizi) go back to 36-39 or (e.g. Aberle) to 37. Belser assigns 41-42; Conély, 40-50; Schafer, 50-51; Hug, Reuschl, Schanz, and Rose, 60-67. This last opinion is founded on the combined testimonies of St. Irenæus and Eusebius, and on the remark inserted parenthetically in the discourse of Jesus in chapter xxiv, 15: “When therefore you shall see the abomination of desolation, which was spoken of by Daniel the prophet, standing in the holy place”: here the author interrupts the sentence and invites the reader to take heed of what follows, viz.: “Then they that are in Judea, let them flee to the mountains.” As there would have been no occasion for a like warning had the destruction of Jerusalem already taken place, Matthew must have written his Gospel before the year 70 (about 65-70 according to Batiffol). Protestant and Liberalistic critics also are greatly at variance as regards the time of the composition of the First Gospel. Zahn sets the date about 61-66, and Godet about 60-66; Keim, Meyer, Holtzmann (in his earlier writings), Beyschlag, and Maclean, before 70, Bartiet about 68-69; W. Allen and Plummer, about 65-75; Hilgenfeld and Holtzmann (in his later writings), soon after 70; B. Weiss and Harnack, about 70-75; Renan, later than 85, Réville, between 69 and 96, Jülicher, in 81-96, Montefiore, about 90-100, Volkmar, in 110; Baur, about 130-34. The following are some of the arguments advanced to prove that the First Gospel was written several years after the Fall of Jerusalem. When Jesus prophesies to His Apostles that they will be delivered up to the councils, scourged in the synagogues, brought before governors and kings for His sake; that they will give testimony of Him, will for Him be hated and driven from city to city (x, 17-23) and when He commissions them to teach all nations and make them His disciples, His words intimate, it is claimed, the lapse of many years, the establishment of the Christian Church in distant parts, and its cruel persecution by the Jews and even by Roman emperors and governors. Moreover, certain sayings of the Lord–such as: “Thou art Peter; and upon this rock I will build my church” (16:18), “If he [thy brother] will not hear them: tell the Church” (xviii, 10)–carry us to a time when the Christian Church was already constituted, a time that could not have been much earlier than the year 100. The fact is, that what was predicted by Our Lord, when He announced future events and established the charter and foundations of His Church, is converted into reality and made coexistent with the writing of the First Gospel. Hence, to give these arguments a probatory value it would be necessary either to deny Christ’s knowledge of the future or to maintain that the teachings embodied in the First Gospel were not authentic.
