Ontology is a kind of philosophical construct popularised by Classical Greek and Roman philosophers, such as the Neoplatonists. They say what things are, without going into finer details and nuances of what is really meant. Theology was one subject turned into ontologies, especially in the second and third centuries AD. Today mistakes are made by using such ontologies as references. It might be that one such mistake is when people see an ontological statement that the Father is divine, and Jesus is divine, but then they infer that Jesus is God, namely the one true God, called the Most High in the scriptures.
