Must be (
dei einai). Since moral conditions are so bad among you (cf. chapters 1 to 6). Cf.
Matthew 18:7 .
Heresies (
airesei). The schisms naturally become
factions or
parties. Cf. strifes (
eride) in
Matthew 1:11 .
See on "Ac 15:5"
for
airesei, a choosing, taking sides, holding views of one party, heresy (our word). "Heresy is theoretical schism, schism practical heresy." Cf.
Titus 3:10 ;
2 Peter 2:1 . In Paul only here and
Galatians 5:20 .
That (
ina). God's purpose in these factions makes
the proved ones (
oi dokimoi) become
manifest (
paneroi). "These
airesei are a magnet attracting unsound and unsettled minds" (Findlay). It has always been so. Instance so-called Christian Science, Russellism, New Thought, etc., today.
