Yes, I know.
But all other, let’s call them protestant, Churches do have open communion.
[Although the Anglican Church and the others mentioned above, are not “typical” protestants for me. They are more “Catholic without a pope”

)
At the moment I am studying the Heidelberg Catechism and the Helvetic Confession (by Heinrich Bullinger), as I really like their theology - it is very similar to the belief of Baptists. And I am at the moment attending a Baptist Church on a regular Basis.
Here a quote concerning Communion:
"Question 81. For whom is the Lord’s supper instituted?
Answer: For those who are truly sorrowful for their sins, and yet trust that these are forgiven them for the sake of Christ; and that their remaining infirmities are covered by his passion and death; and who also earnestly desire to have their faith more and more strengthened, and their lives more holy; but hypocrites, and such as turn not to God with sincere hearts, eat and drink judgment to themselves.
