Does Christianity have any other book beside Bible which narrate stories of the Jesus and Moses and is considered auspicious or sacred? Are there any other such books other than Bible which kind of augments/completes the Bible? In Islam there is the Quran (Bible) and then hadith books which narrates stories of the prophets.
It really depends on which branch of Christianity you're asking about.
The Church of Jesus Christ of Latter-Day Saints (Mormons) recognize the Book of Mormon, the Pearl of Great Price, and the Doctrine and Covenants. They also believe in continuing revelation.
Jehovah's Witnesses use the periodic publications of the Watchtower as authoritative.
The Catholic Church recognizes the Deuterocanon as part of the Bible, which most other Christian faiths do not.
The Community of Christ, formerly Reorganized Church of Jesus Christ of Latter-Day Saints, recognizes the Book of Mormon, the Doctrine and Covenants, and the Revised Common Lectionary.
Seventh Day Adventists use the writings of Ellen White.
