Colossians 2:18
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.
1 Peter 4:17
For the time has [now] come for the house of God [the church, See I Tim. 3:15] to begin receiving judgment [i.e., by undergoing persecution], and if it starts with us [Christians], what will be the [ultimate] end of people who do not obey the Gospel of God?
