Without denial of the fulness of knowledge in the divine nature of Christ, there is a well-known current speculation as to how far His human nature participated in His divine knowledge, and whether any shade of ignorance was permitted to rest upon His human soul, as part of the self-imposed kenosis mentioned in Phil. ii, 7. This idea of kenosis may be wrong, but it is not Arianism. There never was kenosis of the Eternal Son, as such.
