"... life is a unity of body and soul." I use a somewhat more difficult definition: the soul is the behavior mechanism, the will, emotions and mind of the life in the body, with the spireit being the life level raising humans above the animal level. Since I define the behavior mechanism as existing outside of space/time and connected to same via the body (the flesh), I would define the soul as 'timeless' thus eternal (as is the spirit), but the connection mechanism (the body) is definitely under the dictates of space/time in current dispensation.
