Yes, that has been a long standing feature of Baptist practice. Quite early on, centuries ago, a pietistic group of Christians separated from the Church of England to become the foundation of Baptists as we know them, and they adopted complete abstinence from drinking alcohol as a church policy. Anyhow that’s an apparent answer to the Salvation Army communion question. Currently they are permissive towards members going to other churches to get communion. So the gap gets bridged in that manner. I know they told me there was no problem going to a Baptist church for it.
The importance of communion is that it symbolizes the way that Christians imbibe and ingest the Holy Spirit in a spiritual sense. To omit that is to omit a significant witness. Roman Catholics read even more into it, but I’m not going there. At any rate, Christians DO imbibe and ingest the Holy Spirit, both in communion observations and outside of them.
