Great quote from M. Sydney Park about submission in the Christ Hymn of Philippians 2:
“Submission, as portrayed in Philippians, is not the consequence of oppression or coercion. Rather, it is offered freely, and reflects the self-giving character of God in the salvation events (2.6-11). Moreover, as the recipients of that grace, believers are exhorted to demonstrate a similar self-kenotic behaviour/mindset in their mutual relations. Regardless of the context of social order, gender and status, each believer is called to treat the other as a ‘superior’ as Christ submitted to God.”
