There would need to be a Roku app that supports the service on which the video/stream appears. Or the church would need to use a service for which there is already a Roku app.
There is no Facebook video app, so that isn't possible.
Some churches also build their own Roku app for their own video stream, but that is not feasible for all.
My church also broadcasts its services. We use lYouTube, and the YouTube app is how to watch it.
