To admit that Jesus had faith in God during mortality
causes all sorts of problems for Trinitarian Christology. Notice the following
argument:
God doesn't have faith
Jesus had faith
Therefore, Jesus and God are not numerically
identical.
I answer that, As was
said above (II-II, 1, 4), the object of faith is a Divine thing not seen. Now
the habit of virtue, as every other habit, takes its species from the object.
Hence, if we deny that the Divine thing was not seen, we exclude the very
essence of faith. Now from the first moment of His conception Christ saw God's Essence
fully, as will be made clear (34, 1). Hence there could be no faith in Him.
There are many problems with this, not the least is
that it goes against the clear teachings of Hebrews that (1) Christ was human
in all things except being sinful and (2) that Christ is our forerunner:
For verily he took not
on him the nature of angels; but he took on him the seed of Abraham. Wherefore
in all things it behoved him to be made like unto his brethren, that he might
be a merciful and faithful high priest in things pertaining to God, to make
reconciliation for the sins of the people. For in that he himself hath suffered
being tempted, he is able to succour them that are tempted. (Heb 2:16-18)
Which hope we have as
an anchor of the soul, both sure and steadfast, and which entereth into that
within the veil; whither the forerunner is for us entered, even Jesus, made an
high priest for ever after the order of Melchisedec. (Heb 6:19-20)
Again, Trinitarians are in the unenviable position of
having to defend a dogma against both logic and scripture.
