Let us imagine ourselves in Jerusalem in the year One, of the Christian era, when the apostles, as it is claimed, were proclaiming Jesus as the Messiah, crucified and risen. Desiring to be convinced before believing in the strange story, let us suppose the following conversation between the apostles and ourselves. We ask:
How long have you known Jesus?
I have known him for one year.
And I for two.
And I for three.
Has any of you known him for more than three years?
No.
Was he with his apostles for one year or for three?
For one.
