The Apostles did not understand it that way. Says who?
Jesus explicitly told the Jews:
"'I and the Father are one.'
Again the Jews picked up stones to stone him, but Jesus said to them, 'I have shown you many great miracles from the Father. For which of these do you stone me?'
'We are not stoning you for any of these,' replied the Jews, 'but for blasphemy, because you, a mere man, claim to be God'"
John 10:30-33
Well; SOMEbody sure figgered out there was at LEAST a Binary personage in their presense!

Revelation 22:3 NKJV And there shall be no more curse, but the throne of God and of the Lamb shall be in it, and His servants shall serve Him.
A throne does not indicate a person.
