Totally valid question. We are instructed to come together, and edify one another. And do certain things when we come together and as oft as we come together. Christianity is a community. Worship is a community just as much as it is individual. If it were only individual, it would have never survived the roman persecution and flourished.
Can it be watched at home? Sure, we've done it on occasion. Our congregation has a very nice technology set up. We live stream, you tube channel, can even produce concerts. We have a very big and up to date package. Can even do your online contributions and have deducted automatically, for those who travel alot or have jobs that keep them away a lot. Was online the same for me. No. But, that's just me. we have some you may only see on Sunday morning, and not every one at that because they go help smaller congregations in the county maybe on Sunday night, or Wednesday. As a congregation, the elders elected to comply and suspend services in lieu of online. And the full service. Singing. Communion. Sermon. The works. There is a break for you to do communion with family. They've made every accommodation. We have groups of people that have been assigned five families to maintain contact with. I get two calls a week for prayers, needs, etc. Community worship starts with the individual. But, it is no less vital.
