Jesus said to them: 'Amen, amen I say to you, before Abraham was made, I am.'
Is this statement in the other tree Gospels?
No ... all of the gospels contains some unique citations ... as is to be expected from four witnesses.
OTOH ... this statement is from Micah.Micah 5:2 But thou, Bethlehem Ephratah, though thou be little among the thousands of Judah, yet out of thee shall he come forth unto me that is to be ruler in Israel; whose goings forth have been from of old, from everlasting.
Yes, but shouldn't the most important statements be in all four or at least a majority, rather than one?
