This is a great question especially in view of Heb 10:25 which says:
[Do] not giving up meeting together, as some are in the habit of
doing, but encouraging one another--and all the more as you see the
This question can be rephrased as, Must meeting together be a physical meeting or can it be otherwise?
The noun translated "meeting together" here is ἐπισυναγωγή (episunagógé) and only occurs here and in 2 Thess 2:1 which talks about the gathering of the saints to Jesus at His coming. It is from the cognate root συνάγω (sunagó) = to bring or gather together, and occurs frequently in the NT.
Before offering some comments, let me first say that I am a strong believer in meeting together as a local congregation/group (in various ways) on a regular basis to encourage one another, share our faith and learn more about Scripture and Jesus. However, in the current circumstances, is there a NT precedent for meeting in some other way, rather than physically? I believe there is. Here are some examples:
- 1 Cor 5:3, 4, For my part, even though I am not physically present, I am with you in spirit. … So when you are assembled and I am with you in spirit, …
- Phil 1:27, … I'll hear that you are firmly united in spirit, united in fighting for the faith that the Good News brings …
- Phil 2:2, then make my joy complete by being like-minded, having the same love, being one in spirit and of one mind.
- Col 2:5, For though I am absent from you in body, I am present with you in spirit and delight to see how disciplined you are and how firm your faith in Christ is.
- 1 Cor 6:17, But whoever is united with the Lord is one with him in spirit.
- John 4:24, For God is Spirit, so those who worship him must worship in spirit and in truth …
Without going into a detailed exegesis of these passages, I note that one of the various meanings of the Greek word πνεῦμα (pneuma), "spirit" given BDAG is (#3c) "spiritual state, state of mind, disposition". Thus, it might be possible to understand Paul's wish to be absent in body but present by his spirit as a kind of meeting minds. This is a vague approximation of what we moderns now call a virtual meeting online.
Many of Paul's letters (and others) were written precisely because these apostles could not be physically present and so they tried to do this by the written word.
In short, the modern practice of quarantine is a Biblical practice as set out in Leviticus to limit the spread of communicable diseases; and we do well to implement it as we can.
