I understand that it’s wrong to receive Holy Communion in Protestant churches without valid orders (e.g. the Anglican church), because the Church teaches that they don’t have valid orders, and so cannot confect the Eucharist.
But what about churches such as the Church of Scotland (Calvinists) who don’t believe in the real presence in the first place. For the Church of Scotland and its’ offshoots, Holy Communion is only a representation that reminds us of God’s love for us and our community of faith with one another. In some ways, this is similar to the Agape or love meal which the early Christians shared outside the Eucharist.
In a Church of Scotland Church, the Minister is saying “this isn’t really the Body of Christ, it’s just a symbol”, and as a Catholic I can agree with him, that it isn’t the Body of Christ. As a Catholic, would I be sinning by taking part in this?
