Council of Lyons I, 1245

452. 8. Furthermore in the application of water, whether cold or hot or tepid, in the sacrifice of the altar, let the Greeks follow their own custom if they wish, as long as they believe and declare that, when the form of the canon has been preserved, it is accomplished equally by each (kind of water).—9. But let them not preserve the Eucharist consecrated on the day of the Lord's Supper for a year on the pretext of the sick, that with it they may obviously communicate themselves. It may be permitted them, however, in behalf of the sick themselves, to consecrate the body of Christ and to preserve it for fifteen days, but not for a longer period of time, lest through its long preservation, perchance by a change in the species, it be rendered less suitable to receive, although the truth and its efficacy always remain entirely the same, and never by any length of time or the mutability of time do they grow weak.—10. But in the celebration of solemn and other Masses, and concerning the hour of celebrating these, as long as in the preparation and in the consecration they observe the form of words expressed and handed down by the Lord, and (as long as) in celebrating they do not pass the ninth hour, let them be permitted to follow their own custom.

453. 18. Moreover concerning fornication which an unmarried man commits with an unmarried woman, there must not be any doubt at all that it is a mortal sin, since the Apostle declares that "fornicators as adulterers are cast out from the kingdom of God" [I Cor. 6:9].

In addition to this we wish and we expressly command that the Greek bishops in the future confer the seven orders according to the custom of the Roman Church, since they are said to have neglected or to have hitherto omitted three of the minor ones with respect to those to be ordained. But let those who already have been so ordained by them, because of their exceedingly great number, be kept in the orders thus received.

455. 20. Because according to the Apostle "a woman if her husband is dead is freed from the law of her husband" so "that she has the free power of marrying whom she will in the Lord" [cf. Rom. 7:2; I Cor. 7:39], let the Greeks in no measure reprehend second or third or even later marriages; nor should they condemn but rather approve them between persons who otherwise can licitly be united to one another in marriage. Priests, however, should not by any means bless those who marry a second time.

456. 23. Finally, since Truth in the Gospel asserts that "if anyone shall utter blasphemy against the Holy Spirit, neither in this life nor in the future will it be forgiven him" [cf. Matt. 12:32], by this it is granted that certain sins of the present be understood which, however, are forgiven in the future life, and since the Apostle says that "fire will test the work of each one, of what kind it is," and " if any man's work burn,
