These days, returning to church is a big topic amongst those who have a vested interest in these things (presumably Christians, their denominations, and their leaders). Everything from technical adaptations for those who enjoyed worshiping from remote virtual locations to protocols for physical gatherings make up the topics under discussion.
Unfortunately, these preoccupations drag us back into the old paradigm that church happens at particular location at a particular time, and your job is to show up to it, and that constitutes being church.
Of course, the discipline of participating in communal worship is critical to the formation and sustenance of believers, but so easily displaces the many ways we are to be the church. If we are to do any kind of self-evaluation around how we regather as the church in an emerging post-COVID world, then let us reflect on how we embody the life of friendship in our neighbourhoods; how we receive the gifts of grace and providence in the places we work and play; how we engage in movements for justice and reconciliation in the community; how we attend to the needs of our brothers and sisters in Christ in their everyday lives; how we pray and intercede for the kingdom to come; and then, how we show up to our gatherings.
Are you returning? Maybe you never left but didn't recognize it! Be the church, for it is through the church that the wisdom of God will be made known everywhere (Eph.3:10). GS
