What constitutes a Worship Service?

Is it prescribed in the NT?

What is contained within that… prayer, singing, the Eucharist, eating, Bible reading, Bible study, preaching, children’s sermon, child care, flashing hazards indicating a guest…?

Someone declared the Eucharist “had” to be a part of a “Worship Service” for it to be authentic.  I’m not really even sure what that means.  But it will force you down the road of what happens in the Eucharist… ordinance or sacrament… every week or quarterly… means of grace or not… Spirit “within” or “alongside”….
then… also what is a Worship Service, what should be involved, … does it matter?

Be like a Berean.  Acts 17:11.

Good luck.
