O Lord, who shall sojourn in your tent? Who shall dwell on your holy hill? in whose eyes a vile person is despised, but who honors those who fear the Lord; Psalms 15:1&4ab [ESV]
At first glance, the first part of verse 4, “in whose eyes a vile person is despised” might seem Pharisaical. In fact, this is more an assertion of loyalty. He’s not trying to compete or judge; he’s just expressing his preference and his position.
I must be careful not to take passages like this as a ‘right’ to despise an enemy of God; rather the rest of the bible and Jesus Himself commands us to love others including our enemies. What this does do is reinforce how I align my loyalty to my brothers and sisters in Christ over those who would oppose my co-heirs and Christ Himself.
As I live my life, I am to be a ‘light’ in the darkness and blatantly/outwardly expressing a despising of enemies of God is detrimental to being the light God has called me to be. Instead, I am to love my enemy, offering them a drink of water or bread to eat, which will heap burning coals on their head.
If possible, so far as it depends on you, live peaceably with all. Beloved, never avenge yourselves, but leave it to the wrath of God, for it is written, “Vengeance is mine, I will repay, says the Lord.” To the contrary, “if your enemy is hungry, feed him; if he is thirsty, give him something to drink; for by so doing, you will heap burning coals on his head.” Do not be overcome by evil but overcome evil with good.Romans 12:18-21 [ESV]
