The "fig tree" in Matt.24:32 is claimed dogmatically to be Israel. That idea is found nowhere in the entire Holy Bible or Apocrypha. Yet, it is a teaching found with the Gnostics. I quote from the Apocalypse of Peter, found in the Gnostic Society Library online:
"And ye, take ye the likeness thereof (learn a parable) from the fig-tree: so soon as the shoot thereof is come forth and the twigs grown, the end of the world shall come.
And I, Peter, answered and said unto him: Interpret unto me concerning the fig-tree, whereby we shall perceive it; for throughout all its days doth the fig-tree send forth shoots, and every year it bringeth forth its fruit for its master. What then meaneth the parable of the fig-tree? We know it not.
And the Master (Lord) answered and said unto me: Understandest thou not that the fig-tree is the house of Israel?" http://gnosis.org/library/apocpeter.htm
