Galatians 2:1

Fourteen years later. Probably fourteen years after the visit mentioned in Galatians 1:18. [Johnson thinks it should be measured from Paul's conversion to Christ.] This certainly is the Jerusalem Meeting of Acts ch 15, and Ramsay gives the date as 49 A.D. The church began in Jerusalem on Pentecost, 30 A.D. (by the corrected calendar), and Paul's conversion must have been between 31 and 33 A.D. The visit of Galatians 1:18 is probably the same as Acts 9:26. Paul made a second visit (Acts 11:30) which is not mentioned here. Barnabas. Acts 4:36. Titus. Paul seems to have taken Titus as a test case. Many of the Gentile Christians had already been "Gentiles converted to Judaism" before they heard of Christ. Titus was a direct convert from idolatry to Christ. Compare 1 Thessalonians 1:9.
