Gathering still matters
The New Testament treats meeting with other believers as a real gift and responsibility. Christians are not meant to follow Jesus entirely alone. Hebrews urges believers not to give up gathering, but to encourage one another, especially as they await Christ's return (Hebrews 10:25).
That does not mean every congregation must meet in the same room at every moment, whatever the circumstances. The heart of the command is shared worship, mutual encouragement, and faithfulness to Christ. During a serious outbreak, a church can seek those things through smaller meetings, phone calls, prayer, practical help, or other temporary arrangements.
Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching.
Love includes protecting people
Jesus named love for one's neighbour as central to God's command (Mark 12:31). In a pandemic, that love includes considering the elderly, people with health conditions, exhausted medical workers, and households who could be affected by an infection brought home from a gathering.
Paul tells the Philippian church not to focus only on their own interests, but also on the interests of others (Philippians 2:4). So a decision to suspend a crowded service for a season need not come from fear or weak faith. It can be a practical way of putting another person's welfare ahead of personal preference.
Look not every man on his own things, but every man also on the things of others.
Respect public authorities wisely
Romans teaches Christians to recognise governing authorities as part of God's ordering of society (Romans 13:1). Public-health measures are not automatically hostile to faith, particularly when they aim to limit harm and apply fairly to the wider community. Churches can cooperate with reasonable temporary guidance while continuing their ministry in safe ways.
There are limits. When authorities require Christians to disobey God, Peter's principle is clear: God must be obeyed above human commands (Acts 5:29). Yet not meeting in a particular building for a limited time is different from being commanded to deny Christ. Wisdom asks what is being required, why, and whether the church can still faithfully worship and serve.
Let every soul be subject unto the higher powers. For there is no power but of God: the powers that be are ordained of God.
A closure should not become isolation
A building may close, but the church's calling continues. The first believers devoted themselves to teaching, fellowship, prayer, and sharing with people in need (Acts 2:42, Acts 2:45). Those practices can take thoughtful, different forms when ordinary meetings are unsafe.
Church leaders should communicate clearly, keep checking on lonely or vulnerable people, and make space for prayer and pastoral care. Members can ring someone who lives alone, deliver help safely, give generously, and keep encouraging one another. When it becomes reasonably safe to gather again, returning to embodied fellowship is worth pursuing. For a season, though, protecting life and loving neighbours can make a temporary closure a faithful response.
