Our Lord said, "No man can serve two masters. For either he will hate the one, and love the other: or he will sustain the one, and despise the other. You cannot serve God and mammon." (Matthew 6:24)
And He also said, "Every kingdom divided against itself shall be made desolate: and every city or house divided against itself shall not stand." (Matthew 12:25)
Thus, one who was born a Jew and wants to convert to Christianity, must make the decision which master/house he will serve, and plant both of his feet there. instead of planting each foot in a different house, under a different master.
However, if this logic is not enough for you, I wrote an article a year and a half ago, using more Scripture to prove this case:

I also recently made a video using even more sources and logic to prove this case. Please choose whatever streaming service you wish to watch this video:

Dude. Freemasons are essentially Judaism goyim (they basically are tools of the Jews) and Catholics have been denouncing Freemasonry since the 18th Century lol. If you become a Freemason as a Catholic you incur an automatic Excommunication lol. B'nai B'irith is just essentially the Jewish head of goyim Freemasonry. Judeo-Masonry and Catholicism are polar opposites. You really need to be more studious, my friend lol.
