How is it… that the Son and Holy Spirit are not co-unoriginate with the Father, if they are co-eternal with Him? Because they are from Him, though not after Him. ‘Being unoriginate’ necessarily implies ‘being eternal,’ but ‘being eternal’ does not entail ‘being unoriginate,’ so long as the Father is referred to as origin. So because They have a cause They are not unoriginate… a cause is not necessarily prior to its effects… Because time is not involved, They are to that extent unoriginate… for the sources of time are not subject to time.
