We cannot answer all the questions in this overview, but we can exegete the Lord’s Supper in its original context in Matthew, Mark, and Luke. This post also looks very briefly at 1 Corinthians 10:16-17 and 11:23-34. Then, what do various churches teach about the Lord’s Supper (or Communion or Eucharist)? I am here to learn (and offer my own opinions at various times). I updated this post with information that startled me.
