Is calling Jesus the Only Son of God Biblical?
Your answer???
Of course it is, but no one writes articles about that. My comment was directed at the behavior of people who write articles about whether something or other is “Biblical”. Invariably they write articles about things they regard as un-Biblical and invariably “Biblical” means exactly what I described in my second paragraph.
The whole content of the Nicene Creed is Biblical, as was shown quite ably by St. Cyril of Jerusalem in his Catechetical (and Mystagogical) Homilies, provided one doesn’t load one’s notion of what is “Biblical” with hermeneutic preconceptions.
Of course, when one extends the creed to the clauses about the Holy Spirit added by the Second Ecumenical Council, only the original version we Orthodox maintain — no filioque — is Biblical.
