Origen, on 2Thess 2:1

“And we beseech you, brethren, by the coming of our Lord Jesus Christ, and of our gathering together unto him:”

“At least, when the apostles were preaching and the eyewitnesses of Jesus were teaching his precepts, no minor dispute in the church took place among Jewish believers about those of the Gentiles who were converted to the faith; the question was whether they ought to keep the Jewish customs or if the burden of clean or unclean meats ought to be taken away so that it would not be a load upon those Gentiles who abandoned their traditional customs and believed in Jesus. Furthermore, in the epistles of Paul, who was contemporary with those who had seen Jesus, there are some statements to be found which concern certain disputes about the resurrection, and about the view that it had already occurred, and about the question whether the day of the Lord was already present or not.”
