This issue did cause the church some problem early on. Latin provided an easy solution: There are different words for personal enemy (inimicus) and a common enemy (hostis).
So, even though their supposed godboy did not speak Latin, when he said love your 'enemies' he only meant your inimici. The pope would tell you who the hostii were and you were expected to kill those motherfuckers!
