The standard by which all other readings are measured is the Holy Scripture. If an author makes a statement that either has no scriptural backing, or the way the author applies a scripture is weak, then proceed only with great caution. If the book denies Jesus is Lord and has come in the flesh, dispose of the book.
I heard a friend say to a group of ladies the other day, "Women, be patient. Remember what the Buddhists say, 'One mountain, many path's'". I quickly responded, "You just have to make sure you are on the right mountain."
What my friend said had a measure if truth. But the saying can lead to deception, because it teaches all religions lead to God. Jesus said he is only one way to go to the Heavenly Father (John 14:6), and only if the Father draws him (John 6:43). The good news is, there is a measure in which The Father draws each of us (John 1:4-5,9; 3:16; Romans 1:20; Hebrews 2:9; 2 Peter 3:9).
The point is we must know the scripture if we are to use it as a measure. So above all other reading, read the Bible. Then read other Christian authors.
