In the Creed, we confess to believe that the Lord Jesus Christ is “consubstantial with the Father”.
Few of us, however, have ever seen this word “consubstantial” used in any context by which its meaning might be understood.
This evening, I ran into one use, which I think makes its meaning clear.
In his work “On the Free Choice of the Will”, St. Augustine uses the term when speaking about light and heat. He says:
“Light and heat are both perceived consubstantially in the same fire.”
This sentence gives us some material to reflect on as we consider the meaning of the word “consubstantial” in the Nicene Creed.
Saving this for another time…too much reading to get done at present.
