We regard the wearing of masks in worship first of all as a matter of conscience—and since we are forbidden by the teaching of Christ not to make extrabiblical religious rules that bind men's consciences (Matthew 23:1-7; 15:1-9), we neither mandate nor forbid the wearing of masks in worship.
Veils and face coverings have profound religious significance in many world religions. Indeed, much of the rhetoric surrounding COVID masks (even among evangelical Christians) describes them as symbols of personal piety. Serious questions about the usefulness, effectiveness, or medical necessity of masks are routinely dismissed or swept aside, and people are told to wear them simply because they are a tangible, visible means of showing love for one's neighbor. This rationale is pressed on people's consciences regardless of whether it can be proved statistically that they really safeguard anyone from the virus, and irrespective of the fact that masks can cause other medical problems. But COVID masks have become, in effect, secularism's substitute for religious vestments. No one can reasonably deny that face coverings have become the chief symbol of popular culture's sanctimonious devotion to the secularist credo.
