When Paul wrote to Titus, he calls him his son in the common faith. When he wrote to Timothy, he called him his son in the faith. Why did he use the phrase ‘common faith’ when writing to Titus?
Titus was a Gentile and uncircumcised. Timothy had a Jewish mother and was circumcised. Faith has always been the way to come to God, but it didn’t become common to the Gentiles until the message was revealed to Paul.
