You really need to become better informed before you start accusing others of heresy. It was Jesus who said, referring to the end times, “No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father” (Matthew 24: 36; Mark 13: 32). Since Jesus is the Son of God, then by your standards he is a heretic, because he said that he didn’t know.
And one needs to read the bible more carefully when using it as support for a position. The footnote to Matthew reads “with a knowledge He could communicate”. He knows, but it is not for us to know.
