"Canon 58. Concerning those, who show support and favor to the Jews against the faith of Christ. The avarice of some is so great that they therefore seperate themselves from the faith, just as the Apostle expressed it; just as even many among the clergy and laity accept presents from the Jews to aid their perfidy, in that they allow them to enjoy their protection; to those, of whom one knows not without reasons, that they belong to the body of Anti-Christ, since they work against Christ. Every bishop, presbytery or layman, who in the future grants support to them (the Jews) against the Christian faith, be it through briberies or favours, shall be regarded as profane and blaspheming God. He shall be excluded from the Communion of the Catholic Church and be regarded as not belonging to the kingdom of God; for it is no more than right, that those who reveal themselves as protectors of the enemies of the Lord, be seperated from the body of Christ." - Fourth Toledo Council of the Catholic Church

This warning is consistent with what's taught in the Bible, e.g., in 2 John 9-11: "Whoever transgresses and does not abide in the doctrine of Christ does not have God. He who abides in the doctrine of Christ has both the father and the son. If anyone comes to you and does not bring this doctrine, do not receive him into your house nor greet him, for he who greets him shares in his evil deed." (The Holy Bible, 2 John 9-11) "And if thy right hand scandalizeth thee, cut it off and cast it from thee. For it is expedient for thee that one of thy members should perish, rather than that thy whole body go into hell." (Douay-Rheims Bible, Mathew 5:30) Thus, it became official policy of the Catholic Church that those members who yoked themselves with Judaism or Judeo-Freemasonry were cut off from the body of Christ:

Canon 8 * * * *

That Hebrews ought not to be received unless they have been converted in sincerity of heart.

Since certain, erring in the superstitions of the Hebrews, have thought to mock at Christ our God, and feigning to be converted to the religion of Christ do deny him, and in private and secretly keep the Sabbath and observe other Jewish customs, we decree that such persons be not received to communion, nor to prayers, nor into the Church; but let them be openly Hebrews according to their religion, and let them not bring their children to baptism, nor purchase or possess a slave. But if any of them, out of a sincere heart and in faith, is converted and makes profession with his whole heart, setting at naught their customs and observances, and so that others may be convinced and converted, such an one is to be received and baptized, and his children likewise; and let them be taught to take care to hold aloof from the ordinances of the Hebrews. But if they will not do this, let them in no way be received.

"We have resolved and decreed to condemn and forbid such Societies, assemblies, reunions, conventions, aggregations or meetings called either Freemasonic or known under some other denomination. WE CONDEMN AND FORBID THEM BY THIS OUR PRESENT CONSTITUTION, WHICH IS TO BE CONSIDERED VALID FOREVER." -- Pope Clement XII (for more on Freemasonry, visit destroyfreemasonry.com.) "In addressing the state of the Church in Italy, Germany, and Switzerland in his 1873 encyclical Etsi Multa, Pius IX once again strongly warned the faithful about the errors of Freemasonry: 'For from these the synagogue of Satan is formed which draws up its forces, advances its standards, and joins battle against the Church of Christ'".(Masonry Unmasked, John Salza, page 148.)
