"A Christian [Trinitarian] version of the Eye of Providence, emphasizing the triangle representing the Trinity."
The Eye must represent God as a united entity, the three sides representing the three persons of God: the Father, the Son in Hypostatic Union with his Human and Divine natures, and the Holy Ghost/Spirit.
The doctrine of the Trinity teaches "the unity of Father, Son, and Holy Spirit as three persons in one Godhead."
This Trinity Triangle Eye has been used in art as well. See the above Wikipedia article.
