 Leftow characterizes his one-self Trinity theory as “Latin”, following the recent practice of contrasting Western or Latin with Eastern or Greek or “social” Trinity theories. Leftow considers his theory to be in the lineage of some prominent Latin-language theorists. (See the supplementary document on the history of trinitarian doctrines,  section 3.3.2,  on Augustine, and  section 4.1,  on Thomas Aquinas.) In a later discussion Leftow adds that this Trinity theory needn’t commit to trope theory about properties. Rather, whether or not properties are tropes, “…the Father’s having deity = [is numerically identical to] the Son’s having deity. For both are at bottom just God’s having deity.” (Leftow 2007, 358)
