How about Matthew 22: 36-40?

“Teacher, which is the greatest commandment in the Law?”

Jesus replied: “‘Love the Lord your God with all your heart and with all your soul and with all your mind.’ This is the first and greatest commandment. And the second is like it: ‘Love your neighbor as yourself.’ All the Law and the Prophets hang on these two commandments.”

Loving your neighbour as yourself means you don't block them from land they've been using as their home.

1 Corinthians 6:19-20

"Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God?"

Jesus sacrificed his life (his body) for the undeserving sinners of the world. If his body was a temple also, then I think there is a strong argument to be made that the service of others at the cost of damaging a temple is the trade Jesus made.

And if we (Christians) are called to act like Christ, then I think we're on the hook for that.

And, even without that, if you even just came at it from a WWJD perspective... "Hey Jesus, we got some poor hungry cold homeless people up in here, what should we do?" I think "build a fence to keep them out" isn't even close.

Bring them inside! It’s a church for gods sake, they can find a way to aid these people

Maybe give them a place to have fires lol. You're a church you don't pay taxes and your religion calls on you to take care of the unhoused

Hey, if they want to make shit harder on the homeless, they should at least admit that they don't give a fuck about the teachings of the person they claim to worship.
