And though you were once estranged [from God] and were enemies [of His] in your mind because of your evil deeds,

For even though I am absent [from you] in body, still I am present with you in spirit, rejoicing and observing [i.e., with my mind's eye] your orderly behavior and the firmness of your faith in Christ.

Do not allow anyone, who delights in acting humble [i.e., living an ascetic life] and who worships angels, to rob you of your reward [in heaven]. [Note: This "angel worship" could mean holding angels in high regard because of their role as God's messengers, or the claim that God can be approached only through angelic intermediaries]. He places great importance on what he [claims to] see [i.e., visions], being inflated with pride by his fleshly mind for no [good] reason.
