Is the Book of Enoch authentic? I grew up reading the Holy Bible which portrays God as a loving Father, full of compassion and goodwill for mankind. However, after reading the Book of Enoch, I am perplexed at the way heaven and God are portrayed. I was filled with fear and I kept asking myself is this the God Christ reflected while on Earth. My question is that is the Book of Enoch canonical?
The Old Testament canon for Christians was formally set for all five ancient Church Sees (Rome, Constantinople, Antioch, Alexandria, Jerusalem) at the 7th Ecumenical Council in 787.  This Council ratified the Old Testament canons of the local councils of Carthage in 397 and Trullo in 692.  The council of Trullo had ratified the canon specified Canon LXXXV of the Apostolic Canons. 

In neither these local councils nor in the 7th Ecumenical Council was the Book of Enoch specified as one of the canonical Old Testament books.  The canon that the 7th Ecumenical Council ratified was the combined lists of the two aforementioned local councils:


  
  Genesis, Exodus, Leviticus, Numbers, Deuteronomy
  Joshua, Judges, Ruth
  Four "Books of Kings", namely 1/2 Samuel and 1/2 Kings
  Two "books of Paraleipomena", i.e. 1/2 Chronicles
  Job
  Psalms
  Five "books of Solomon": Proverbs, Ecclesiastes, Song of Songs, Wisdom of Solomon, and Wisdom of Sirach (Ecclesiasticus)
  The books of the 12 Prophets: Hosea, Amos, Micah, Joel, Obadiah, Jonah, Nahum, Habakkuk, Zephaniah, Haggai, Zechariah, Malachi
  Isaiah, Jeremiah, Ezekiel, Daniel
  Tobit
  Judith
  Esther
  Two "books of Esdras": Ezra and Nehemiah
  Three books of Maccabees
