It's Biblical is not a catch phrase.

Luke 12:49-56

I have come to set the world on fire, and I wish it were already burning! 50 I have a terrible baptism of suffering ahead of me, and I am under a heavy burden until it is accomplished. 51 Do you think I have come to bring peace to the earth? No, I have come to divide people against each other! 52 From now on families will be split apart, three in favor of me, and two against—or two in favor and three against.

53 ‘Father will be divided against son and son against father; mother against daughter and daughter against mother; and mother-in-law against daughter-in-law and daughter-in-law against mother-in-law.’[a]”

54 Then Jesus turned to the crowd and said, “When you see clouds beginning to form in the west, you say, ‘Here comes a shower.’ And you are right. 55 When the south wind blows, you say, ‘Today will be a scorcher.’ And it is. 56 You fools! You know how to interpret the weather signs of the earth and sky, but you don’t know how to interpret the present times.
