If this Mass did not compromise his readiness and he never missed a call, I'm calling this cop OK.
As a Christian thing, one might try to avoid looking questionable if a choice exists.
In Catholic tradition the mass is considered to be the peak remembrance of Christ. Other Christian traditions don’t always point up the communion in that manner, especially when using a bible interpretation of the elements as symbolic. I’ve seen an exception and it was in a black Missionary Baptist church. They proclaimed the elements as an emblem of Christ and they were picked up by communicants in a combined package. The excitement was tangible. And that’s how it ought to be. If one is being Protestant about it, don’t make it lukewarm too.
Anyhow it’s an appearance thing here. Jesus said go into all the world. If this can be done without looking like it has to be interrupted — it should. This frames Jesus in the best light.
