One great eye-opener is Pauls writings in the 1 Corinthians chapter 7:
27 Are you pledged to a woman? Do not seek to be released. Are you free from such a commitment? Do not look for a wife. 28 But if you do marry, you have not sinned; and if a virgin marries, she has not sinned. But those who marry will face many troubles in this life, and I want to spare you this.
29 What I mean, brothers and sisters, is that the time is short. From now on those who have wives should live as if they do not; 30 those who mourn, as if they did not; those who are happy, as if they were not; those who buy something, as if it were not theirs to keep; 31 those who use the things of the world, as if not engrossed in them. For this world in its present form is passing away.
Paul tells the christians in Corinth not to get married and have families, because the world was going to its end. This is exactley the same cultish bullshit we are familiar to from the JW. This was written some 1950 years ago. We can just speculate about how many of the first christians that were fooled by that doomsday expections. Christianity was a doomsday cult since it's beginning.
