noun
enemy
EN-uh-mee/ˈenəmi/
Someone or something hostile to or working against another.
Each hostile chess player regards the opponent across the board as an enemy.

Etymology
The pieces literally mean “not a friend,” but the Latin compound already meant hostile or unfriendly. Enemy therefore names an active adversary, not merely someone outside one's circle of friends.
In context
the enemy is whispering in a lot of ears today to the church you're not going to make it
