Unity with other religions is a Mortal sin. Pope Eugene 4th Council of Florence, “Cantate Domino” - 1441 Ex Cathedra : The Traditional Holy Roman Church firmly believes, professors and preachers that all those who are outside the Traditional Catholic Church, not only pagans but also Jews or Heretics and Schismatics, cannot share in eternal life and will go into the everlasting fire which was prepared for the devil and his angels, unless they are joined to the Traditional Catholic Church before the end of their lives; that the unity of this ecclesiastical body is of such importance that only for those who abide in it do the church's sacraments contribute to Salvation and do fasts, almsgiving and other works of piety, and practices of the Christian Militant produce Eternal Rewards; and that nobody can be saved, no matter how much he has given away in arms and even if he has shed blood in the name of Jesus Christ, unless he has preserved in the bosom and unity of the Catholic Church !!! St Pope Gregory the Great, Summo Iugiter Studio 590 to 604 : The holy traditional Universal Catholic Church teachers that it is not possible to worship God truly except in her and asserts that all who are outside of her will not be saved !!! That includes Vatican 2 Church, sspx,sspv,cmri,fssp…. For there many Heretics. Pope Pius XI,Rerum Omnium Perturbationem, (# 4), Jan 26, 1923 … the heresies begotten by the Protestant Reformation. It is in these heresies that we discover the beginnings of that apostasy of mankind, from the one, true, traditional catholic church !!! Pope Leo XIII, “UbI Primum” (# 14) may 5,1824 : it is impossible for the most true God who is truth itself the best the wisest provider and the rewarder of Good Men to approve all sects denominations who profess false teachings which are often inconsistent with one another and contradictory and to confer Eternal rewards on their members… by Divine faith we hold one Lord One Faith one baptism that is why we profess that there is no salvation outside the Traditional catholic church. Not the Freemason modernist, Progressive, condemned Vatican 2 Church !!!

Educate those that are incompetent. If they refuse to grow, cut them off.

Without the 'gift of the Holy Spirit' one is not even a Christian! So I guess you mean something else? The Bible also warns against things, that destroy unity. Is the Bible wrong to point that out too?

I don't think think. Are you available to discuss?

Why would you come up with another reason, then the Bible has given in Genesis 11, namely making a name for themselves and refusing God's commandment of spreading throughout the earth? Do you know better than God? How silly your argument is too! You think all their millions of descendants would fit into that tower? And that God couldn't flood it too, if He wanted? But He promised to not flood the entire earth anymore. How far away from God are you?!
