Therefore from now on know we no man after the flesh: yea, though we have known Christ after the flesh, yet from now on know we him no more.

Ambrosiaster
AD 400
Now that Christ has risen from the dead, birth according to the flesh loses its importance, bodily weakness ceases to count and the sufferings of death no longer matter either. Right up until the cross there was a suspicion that Christ was weak, but once he rose from the dead all that vanished and what was previously doubted came to be believed. Commentary on Paul’s Epistles.
