A couple comments..take them or trash them..
1) Age at baptism.."he that believes and is baptized"..no given age, but one must be able understand what it is about.
2) Is fermented wine mandatory at communion?
Our communion is derived from the last supper.
At the last supper, all we have in scripture is that Jesus drank from "the cup" ! The Bible does not say whether it is juice, fermented wine, vinegar or water.
Check it out.. https://biblehub.com/matthew/26-27.htm
Whether one follows the transubstantiation, consubstantiation or memorial only pattern..it evidently makes little difference..since we can offer the same
respect/belief..whether drinking wine, juice, vinegar or water.
Even if one believes in transubstantiation, God obviously can turn any of those liquids into blood.
Of those various translations, only two say "wine". Also, one version replaces "cup" with "chalice"..so I suspect those three versions of taking liberties.
I find no place in the Bible that forbids drinking fermented wine, although there are many which condemn overly drinking.
There is evidently, one exception to the drunkenness rule.. to be found in (Prov 31:6)..
" Give strong drink to the one who is perishing, and wine to those in bitter distress;"
