I can honestly say I didn’t anticipate someone on Lemmy actually pulling a Book of Order reference (and I was way too lazy to look it up this morning).
Also, I think the Baptists also believe in one baptism (but again, only believers, so infants who were baptized need to be re-baptized for Baptists to recognize it). So I guess no double dipping Oreos for either.
If you want an actual answer, I can! Baptists believe that baptism must mimic the baptisms performed by John the Baptist, so they must be believers baptism (no infants) and, most importantly to the meme, full immersion. Presbyterians believe that infants can be baptized and raised in the faith and that any form of water getting on the baptized person (sprinkle, pour, or dunk) is acceptable.
The Baptist thinks the Presbyterian is a heretic, other Presbyterians think this Presbyterian is a heretic if they believe this is the only acceptable way of doing it.
There is a communion practice called “intinction” where the bread is dipped in the juice/wine. Probably not common in traditions that use “host” (crackers, but actually closer to styrofoam), but it is a thing.
