Let's take a look at some samples:
One of the trademarks of a cult is that they divide families. The family is an important source of support for most people. A cult wants its members to be vulnerable and dependent on the cult, so other means of support need to be cut off.
Matthew 8:21 And another of his disciples said unto him, Lord, suffer me first to go and bury my father. 8:22 But Jesus said unto him, Follow me; and let the dead bury their dead.Jesus tells the disciple to value the religion more than closure with his father. I'm of the opinion that funerals are for the living so that they can come to terms with the loss and remember the good times with the dearly departed.
Matthew 10:20 For it is not ye that speak, but the Spirit of your Father which speaketh in you. 10:21 And the brother shall deliver up the brother to death, and the father the child: and the children shall rise up against their parents, and cause them to be put to death.Granted, cultural change tends to cause a lot of friction, but this passage just seems to relish in the idea of families tearing themselves limb from limb.
Matthew 10:34 Think not that I am come to send peace on earth: I came not to send peace, but a sword. 10:35 For I am come to set a man at variance against his father, and the daughter against her mother, and the daughter in law against her mother in law. 10:36 And a man's foes shall be they of his own household. 10:37 He that loveth father or mother more than me is not worthy of me: and he that loveth son or daughter more than me is not worthy of me.The message is clear: God is possessive and needy. The cult is more important than your loved ones.
Matthew 12:46 While he yet talked to the people, behold, his mother and his brethren stood without, desiring to speak with him. 12:47 Then one said unto him, Behold, thy mother and thy brethren stand without, desiring to speak with thee. 12:48 But he answered and said unto him that told him, Who is my mother? and who are my brethren?Jesus wouldn't even acknowledge his family when they wanted to talk to him.
Matthew 15:4 For God commanded, saying, Honour thy father and mother: and, He that curseth father or mother, let him die the death.It's rather strange to hear him defend parents, but it looks like he's still supporting bloodlust as a means to resolve family conflict.
Matthew 19:12 For there are some eunuchs, which were so born from their mother's womb: and there are some eunuchs, which were made eunuchs of men: and there be eunuchs, which have made themselves eunuchs for the kingdom of heaven's sake. He that is able to receive it, let him receive it.There are a lot of cults that stress virginity and asexuality to the point of castration. I'm not sure, but I think this is often meant to target people with longstanding romantic troubles, to free them from the desires that cause them trouble.
Matthew 19:29 And every one that hath forsaken houses, or brethren, or sisters, or father, or mother, or wife, or children, or lands, for my name's sake, shall receive an hundredfold, and shall inherit everlasting life.Abandon your family and your country for the cult, and the big man'll make it worth your while.
23:9 And call no man your father upon the earth: for one is your Father, which is in heaven.Yeah, don't honor the guy who (I hope) raised you with love and care, honor the cult's idol instead.
And that's just the book of Matthew, only about warped family values. This was some of the early stuff that got me started on the road to atheism. Reading the Bible is usually one of the first steps towards deconversion.
