Thomas Aquinas,
Summa Theologiae — Question 11 - OF THE KNOWLEDGE IMPRINTED OR INFUSED IN THE SOUL OF CHRIST…
“ Now the connatural mode of the human soul is that it should understand sometimes actually, and sometimes potentially. But the medium between a pure power and a completed act is a habit: and extremes and medium are of the same genus. Thus it is plain that it is the connatural mode of the human soul to receive knowledge as a habit. Hence it must be said that the knowledge imprinted on the soul of Christ was habitual, for He could use it when He pleased. ”
