....
A: What was the things Paul delivered to them, B: who did he give it to a person, a group, and C: when did that transmission take place. D: I would like a primary historic source please.
A: Paul personally delivered to them (preached/taught to them) all the things that Jesus commanded the apostles to teach. [Matthew 28:19-20; 2 Corinthians 12:1-7] Paul supplemented his oral preaching with his written epistles. [1 Corinthians 14:37; 1 Corinthians 14:37]
Paul and the other apostles delivered to the members of the individual churches many things in person which were not written down. [John 21:25; 1 Thessalonians 3:9-10; 3 John 1:13]
God never commanded the apostles and disciples to write letters to individuals or to various churches or to write down the history of Jesus' life and death and resurrection, except for John; he was commanded to send letters to the seven churches in Asia.
Paul admonishes the churches to hold fast to the traditions that he delivered to them both in person and by the written word in his epistles. [2 Thessalonians 2:15; 2 Thessalonians 3:14]
Jesus never wrote His teachings down on scrolls or papyrus. Likewise, He never commanded His apostles to write down His teachings. Jesus commanded His apostles to make disciples for Him and to teach/preach His gospel to His disciples in person. [2 Timothy 4:2; 1 Timothy 4:11; 2 Timothy 2:2]
B: A body of believers in the local church in Thessalonica;
C: Sometime after his first journey there.
D. Perhaps a Biblical historian can help you with more source material.
Also please point me to the infallible interpretation of the Roman Catholic Church for the passage in question. As that is the interpretation you are bound to other wise you are using your own fallible interpretation.
I know of no source for an infallible interpretation/proclamation/doctrine/dogma on this particular passage. I don't think one exists. Rome rarely makes infallible proclamations and so usually only does make them when there is a big debate raging concerning things pertaining to faith and morals.
However, we do have the opinions of various church and biblical scholars written in the footnotes and notes and commentaries of several of the Catholic Bible translations, but on some passages their opinions do not match. Their own commentaries reflect their own opinions.
My interpretation of Scripture is my own opinion based upon my own study of Scripture and my study of various opinions of others. I use my own reasoning ability to discern if I share any of their opinions and I do not ever claim that my own opinion is infallible. I do my best to make sure that my opinion does not conflict with Catholic doctrine.
Augustine- The Church is the realm of Christ, His mystical body and His bride, the Mother of Christians. He also speaks of an inner and outer church, and the difficulty of telling from appearances who are members of this true church (the "enclosed garden spring shut up, fountain sealed, the paradise with the fruit of apples) who are the elect, and belong to the "invisible fellowship of love
Rounds out the historical meaning of the Church, and it is not restricted to Rome. It would be all his elect and it is catholic is the real sense, not (C)atholic as a name church (visible fellowship)
Rome is where the overseer steward of Jesus' Catholic Church lives and Rome is the seat of his own personal bishopric territory. That is why the pope is called the bishop of Rome. He is also the overseer bishop of the whole Catholic Church.
Jesus appointed one man to the office of overseer steward and this was done by changing his name from Simon to Peter and by giving him the keys. Just as Abram received his new name Abraham when he was chosen to become the father of many nations, Simon also received a new name when he was chosen to became the father of all the members of Jesus' church. The other apostles and their successors came to be known as fathers, but Peter and his successors were specifically chosen above all others to receive the keys designating the office of overseer stewardship.
There can only be one legitimate overseer of all other stewards in office at a time. [Isaiah 22:15-22; Matthew 16:17-19] There were twelve apostles appointed as stewards by Jesus. [1 Corinthians 9:17; Titus 1:7] When Judas hanged himself, another steward was appointed to fill his vacant office. [Psalm 109:8; Acts 1:16-25]
There is only one true Church of Jesus Christ, properly speaking, and it is the Catholic Church and it is headed by the Pope/Papa who alone was given the keys of the kingdom of God. All other organizations who name their assemblies
church are not teaching the whole truth of the church that Jesus established. They teach some truth, which is good, but they are lacking the whole truth.
There can only be one gospel of Jesus Christ and it is taught by Jesus Christ's Catholic Church. All other assemblies (
churches) teach a gospel that is somewhat contrary to the gospel of Jesus Christ. In other words, they ignorantly teach some truth and some error.
Galatians 1:6-9 "I am astonished that you are so quickly deserting him who called you in the grace of Christ and turning to a different gospel 7 not that there is another gospel, but there are some who trouble you and want to
pervert the gospel of Christ. 8 But even if we, or an angel from heaven, should preach to you a gospel contrary to that which we preached to you, let him be accursed. 9 As we have said before, so now I say again, If any one is preaching to you a gospel contrary to that which you received, let him be accursed." RSV
2 Peter 3:15-17 "And count the forbearance of our Lord as salvation. So also our beloved brother Paul wrote to you according to the wisdom given him, 16 speaking of this as he does in all his letters.
There are some things in them hard to understand, which the ignorant and unstable twist to their own destruction, as they do the other scriptures. 17 You therefore, beloved, knowing this beforehand, beware lest you be carried away with the error of lawless men and lose your own stability." RSV
Most people who are living today are ignorant of the true teachings of the gospel of Jesus Christ. This includes most Catholics; they neither know nor do they understand the faith that they were baptized into. I, myself, am still ignorant about many things, but I am doing my best, with God's help, to gain wisdom.
There is only one church in heaven and so everyone there believes exactly the same doctrines.
The
elect of God who are still living on earth are known by God alone according to His foreknowledge. God alone knows the status of each person's soul/heart. [1 Peter 1:2; 2 Peter 1:10; 1 Corinthians 4:5]
