Which places were outlined in Paul's missionary journeys?

Answer 1

In his undisputed letters Paul gives us no information about the first missionary journey and only sparse and contradictory information about the second and third missionary journeys described in Acts of the Apostles. In fact, Raymond E. Brown (An Introduction to the New Testament) says the the three journeys are only a convenient classification developed by students of Acts. Apart from the total lack of first hand evidence for the first journey, doubt has been raised about other aspects of the itinerary.

According to Acts:

First missionary journey:

Antioch, Seleucia, Salamis, Cyprus, South Galatia, Antioch, Jerusalem.

Second missionary journey:

Syria and Cilicia, South Galatia, Phrygia and North Galatia, Mysia and Troas, Philippi, Amphipolis, Apollonia, Thessalonia, Beroea, Athens, Corinth, Cenchreae, Ephesus, Caesarea Maritima, Jerusalem.

Third missionary journey:

North Galatia and Phrygia, Ephesus, Macedonia, Achaia, Macedonia and Philippi, Troas, Miletus, Tyre, Ptolemais, Caesarea, Jerusalem.
