The Galatians, soon after St. Paul had preached the Gospel to them,
were seduced by some false teachers, who had been Jews and who were for
obliging all Christians, even those who had been Gentiles, to observe
circumcision and the other ceremonies of the Mosaical law. In this
Epistle, he refutes the pernicious doctrine of those teachers and also
their calumny against his mission and apostleship. The subject matter
of this Epistle is much the same as that to the Romans. It was written
at Ephesus, about twenty-three years after our Lord's Ascension.
