Step-by-step explanation:
Artwork that depicts the heroes of our faith and reminds us that we belong to the communion of saints is known as iconography. Such artwork can represent a variety of sacred subjects, including Christ, saints, and events from the Bible or the lives of saints. Iconography serves to provide examples of firm faith and virtue, to offer a connection to the divine, and to celebrate the sacred mysteries of the Christian tradition such as the Eucharist. Indeed, these images, like that of the Communion of the Apostles, have played a significant role in connecting worshippers with the spiritual lineage of their faith.
Iconic examples, such as Michelangelo's depiction of saints 'sewing the seeds of faith' or the Romanesque Christ in Majesty, focus on the saints' firm faith and martyrdom, serving as a visual sermon for the viewer. Furthermore, these sacred images often depicted saints in a way that made them appear as active participants in church services, reinforcing the idea that the holy and the faithful are united in worship both in heaven and on earth.
