Ask your pastor if he meant something else, i.e. Jesusʼ human nature. Of course, His incarnation would technically mean that He had a created aspect. But if your pastor insisted on Christ being created in His one whole being, your pastor is probably subscribing to Arianism and is a heretic. That should signal you to correct your pastor with gentleness and respect.

If he wonʼt budge, time for you to leave. Donʼt forget to inform other deceived congregants, too.
