1 Corinthians 10:21-22
You cannot drink [both] the cup of the Lord and the cup of evil spirits [i.e., and still be acceptable to God]. You cannot share in [both] the Lord's table and the table of evil spirits [and still be acceptable to God].
2 Corinthians 6:14-16
Do not team up with unbelievers [i.e., in close relationships, such as marriage, etc.]. For what do righteousness and wickedness have in common? Or, what fellowship can light have with darkness?
Colossians 2:18-19
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 John 5:20-21
And [in addition], we know that the Son of God has come [in a physical body, See 4:2] and has given us understanding, so that we can know the True One [i.e., God], and that we are in [fellowship with] the True One, even His Son Jesus Christ. This Son is the true God and eternal life.
Revelation 22:15
On the outside [of the city] are the dogs [Note: This probably refers to people who practiced sexual perversions. See Deut. 23:17] and the sorcerers, and the sexually immoral people, and the murderers, and the idolaters and every person who loves and practices falsehood.
