Elohim obviously isn’t always plural.
It bears repeating ->
elohim is a Hebrew word which is always, without exception,
plural in form but
almost never plural in meaning.
“Jesus of Nazareth is the Messiah, Son of the living God.” - Peter’s confession (Matthew 16:16).
Jesus of Nazareth is the Messiah, Son of the living
elohim.
In the confession, I substituted the Hebrew word
elohim, which is only and aways plural in form. Jesus isn’t the Son of the living gods.
Jesus of Nazareth is the Messiah, Son of the living
theos.
In the confession, I substituted the Greek word
theos, which is singular.
Jesus is the Son of the living God
elohim / theos.
In Peter’s confession, there is no plurality in the word ”God”. It isn’t plural in English. It isn’t plural in Greek. It isn’t plural in Hebrew. It is singular in all three languages.
P.S.
Jesus of Nazareth is the Son of the Father. It is the Father who is the living God.
