To understand whether the concept of 'participation' in the theology of St. Maximus the Confessor can be understood as a form of sacramental ontology, we must first grasp the meaning of 'participation' in his theological framework.

This participation is not limited to the spiritual realm but extends to the material world as well.

Sacramental ontology refers to the idea that the sacraments are not just symbolic expressions of God's presence but actual means of participating in God's being. In this context, we can see that Maximus' concept of participation aligns with sacramental ontology. He views the sacraments, particularly baptism and the Lord's Supper, as means of participating in God's being and experiencing His presence. This is evident in his writings, where he emphasizes the importance of the sacraments as a means of spiritual growth and union with God.

Maximus' emphasis on the sacraments as means of participating in God's being and experiencing His presence aligns with the sacramental ontology. This understanding highlights the significance of the sacraments in Maximus' theological framework, underscoring their importance in facilitating a deeper relationship with God.
