In Epistolam D. Pauli Apostoli ad Galatas notae

The summary is: Paul had taught the Gospel, that we are justified by faith alone in Christ, or that we receive the remission of sins; the pseudo-apostles were mixing in circumcision and the merits of works. He reproves the fickleness of the Galatians, that they had been alienated so quickly from the truth of the Gospel.

It is to be observed that as often as merit, whether from Sacraments or from other works, is mixed with faith, it is another Gospel, not that of Christ, indeed an overturning of the Gospel from its very foundations.

Let us apply this doctrine to our own times. Paul fights for this principal proposition of the Gospel: We are justified (or absolved from sins) by faith alone in Christ, not by circumcision.

Satan opposes the same proposition today, but under a different color. For he opposes this equivalent: By faith alone (that is, the confidence that he was delivered to death for us, and that we are united to him) we receive Christ, who is our justice. For Satan adds that we receive Christ by mouth. Let us see the counsel of Satan from the effect: Do not many seek the remission of sins enclosed in the host? And what wonder, if they wish to receive justice, or the remission of sins, by mouth, when they have been taught that they receive Christ by mouth? But the articles of faith teach you far otherwise, and the Apostle Paul in Romans 4, verses 10 and 11, expressly opposes that fiction. Therefore, this is another Gospel, and an inversion of the Gospel of Christ. Think now to what danger you expose yourself. But if it remains true and constant
