Armstrong AME Church in Arlington has a small congregation, so it was easy to spot an unexpected visitor Sunday.
A white man in his late 20s who was acting strange entered the church.
It sent a chilling reminder of the Charleston shootings.
The man said he'd gone there for help. Pastor Andre Waits says everything changed when the man explained he recently gone off the deep end.
That's when police were called.
It turns out the man was homeless.
Police determined he meant no harm and let him go on his way.
The incident forced the church to think about what it should do in an institution that has always believed it should keep its doors open to all who want to enter.
The pastor says his church was met with a second challenge on Sunday.
A second homeless person entered the church at the end of the service. He was African-American.
He wanted food. He was helped and sent on his way, too.
There is a homeless shelter a block away which explains the two unexpected visitors.
Pastor Waits says while they looked for a possible threat each time, they want to think they treated both men the same.
