OFFICIAL CATHOLIC TEACHING
Pope Eugene IV, Council of Florence, 1441, ex cathedra:
“The Holy Roman Church firmly believes, professes and teaches that the
matter pertaining to the law of the Old Testament, the Mosaic law, which are
divided into ceremonies, sacred rites, sacrifices, and sacraments, because they
were established to signify something in the future, although they were suited to
the divine worship at that time, after our Lord’s coming had been signified by
them, ceased, and the sacraments of the New Testament began; and that
whoever, even after the passion, placed hope in these matters of the law and
submitted himself to them as necessary for salvation, as if faith in Christ could
not save without them, sinned mortally. Yet it does not deny that after the
passion of Christ up to the promulgation of the Gospel they could have been
observed until they were believed to be in no way necessary for salvation; but
after the promulgation of the Gospel it asserts that they cannot be observed
without the loss of eternal salvation. All, therefore, who after that time [the
promulgation of the Gospel] observe circumcision and the Sabbath and the
other requirements of the law, the holy Roman Church declares alien to the
Christian faith and not in the least fit to participate in eternal salvation.”
