Poussin, Nicolas (1594 Les Andelys - 1665 Rome) – The Sacrament of the Eucharist Part 3 Louvre

The picture has something of this: people, group, woman, wear, monk, child, god, many, prayer, man, church, robe, ceremony, priest, spirituality.
Perhaps it’s a painting of a group of people standing around a table with a man in the middle of the room holding his hand up to a woman’s hand.
