What does it mean to be 'in the form of God'? Is it just an outward show, or something much deeper?
The phrase 'in the form of God' (morphē Theou) doesn't refer to a mere outward appearance or shape. Instead, it points to the very essence and intrinsic nature of God. When applied to Christ, it signifies His true, divine being, sharing in the fundamental nature and character of God from eternity.
This is distinct from a changeable 'fashion' (schēma). Think of it like this: the 'form' of a substance is its fundamental identity, while its 'fashion' might be its temporary appearance. Christ's 'form of God' means His existence was intrinsically divine, not just a temporary divine disguise or a display of power.
