There are fourteen Pauline epistles, letters generally attributed to the apostle Paul. The Greek name for a letter was epistle (ἐπιστολὴ). Nine of these Pauline epistles were addressed to seven Christian Churches that he had visited. 1 Thessalonians, from the early 50s CE, is perhaps the oldest document of the New Testament. 2 Thessalonians dates from the early to late 60s CE. The letter to the Romans was composed between 53-57 CE. 1 Corinthians and 2 Corinthians date from 53-57 CE also. The letter to the Galatians comes from the late 50s CE), while the letter to the Colossians dates from the late 50s to the early 60s CE. The letters to the churches of the Ephesians and the Philippians comes from the early 60s CE. A lot of Christian theology has been based on the reflections of these letters that were describing what was happening in their early Christian communities.
Byblos was the Greek name for an important ancient Phoenician city sometimes called Gebal. Today the town of Byblos is 25 miles north of Beirut, Lebanon, in the Mount Lebanon area on the Mediterranean seacoast. There have been inhabitants in this town continuously for over 5,000 years. Byblos had a major papyrus trade between Greece and Egypt. Thus, the Greek name of Byblos came to dominate. In fact, some Byblos written inscriptions that were discovered in the 20th century, date from around 1,700 to 1,400 BCE.
