This verse shortly sums up all that we have in the Gospel of the history of the first twelve years of our Saviour's life. Though there could be no accession to the perfection of the Divine nature in Christ, yet as to his human nature he was (as we are) capable of accession of habits, and wisdom and knowledge; for though the Divine nature was personally united to the human nature, yet there was no communication of properties.
