Various is the correct author for any book with multiple unknown authors, and is acceptable for books with multiple known authors, especially if not all are known or the list is very long (over 50).
If an editor is known, however, Various is not necessary. List the name of the editor as the primary author (with role "editor"). Contributing authors' names follow it.
Note: WorldCat is an excellent resource for finding author information and contents of anthologies.
It truly is another testament of Jesus Christ. Filled with the word of God. I believe every word and so glad I can know more about my Savior. He loves us all and this book has guided me to know of Gods will. Already started reading it again. Goal this coming year is to not miss a day in reading this book.
