It is selfish to want to be safe? I disagree with that. However, if the government mandates that cover the church/church community say that everyone needs to wear masks indoors, then the church should absolutely follow that mandate. Right now there are no mandates that church attendees need to be vaccinated so there is no way for a church to make that a requirement of attendance (and I don't think that it ever will be). That said, we have not attended in person church since early March 2020 other than one Sunday my husband was asked to preach at our old church because the entire pastoral staff was exposed to Covid and in quarantine. When he went, he stayed completely separate from everyone, only entering the sanctuary to preach and then he left without hanging out with people. This has been because he has 70% lung capacity on a good day due to asthma and this virus could easily kill him so we have instead done online church with our new church, facilitating the online discussion.
But that said, I'm really saddened by the response to this virus and the government mandates amongst church people. At one time I felt the church cared about people's lives and were willing to sacrifice for them but I see now that comfort is more important. What the world is seeing of the church is something that I believe hurts the cause of Christ and certainly is not at all how Christ responded to people. It has me really disillusioned.
