Exposition at a Methodist Wedding?
Can the Eucharist be displayed in a Methodist church for a Catholic wedding?
I am unaware of any rite of the Church that would include such a situation. The Church does not have adoration during a Catholic wedding, so it would not make sense for there to be adoration at a non-Catholic liturgy. When exposition takes place, the prayers and focus should be on the presence of Christ in the Eucharist and not on another activity (Eucharistiae Sacramentum 82), and I'm not sure how that would be possible in a liturgy that denies the Real Presence of Christ in the sacrament of the Eucharist.
Since there are no rituals for such a situation, it should never take place (Redemptionis Sacramentum 137).
