Israels, Isaac – Processie in de Oud-Katholieke kerk te Den Haag, 1881 Rijksmuseum: part 3

The picture has something of this: church, saint, god, people, holy, book, cross, spirituality, religious, priest, sacred, prayer, traditional, worship, sculpture, symbol.
Perhaps it’s a painting of a priest holding a chalice in front of a group of men wearing robes and holding a crucifix.
