In his book...
In his book, "Our Belief," His Holiness Ayatullahelozma Makarem Shirazi states: "We believe that, for the guidance of man, God sent down several divine books, among which we may name: the Sohof, given to Noah; the Law, given to Moses; the Gospel, given to Jesus; and the Qur'an, given to Mohammad.
Unfortunately, through long elapses of time, many of the scriptures have been tampered with and altered to some extent by the interference of ignorant and unauthorized people, resulting in the replacement of some incorrect and immoral ideas.
Among these as an exception is the Glorious Qur'an which has remain unaltered and is exactly the same as it was; and it has always been shining like the bright sun, throughout the ages and the nations, alighting hearts." Not surprisingly, there are Christians who support the notion of the infallibility and inerrancy of the Bible. One Christian apologist writes, "Since God is truth (John 3:33, Romans 3:4), what is breathed out by God, must also be true (John 17:17) and infallible.
Due to the infallible character of God (Titus 1:2), the Son (John 14:6) and the Holy Spirit (1 John 5:6,7), the Scripture which is inspired by God is also inerrant in every aspect (Matt 22:43-45, Matt 22:32, and Gal 3:16). The Old Testament also attests the inerrancy of the Bible.
The word of the Lord is flawless (Psalms 12:6), it is eternal and stands firm (Psalms 119:89), and that every word of God is flawless (Proverbs 30:5-6)." How Christians and Muslims understand the texts and prophecies of their respective traditions is important because they can influence the ways in which they interpret issues such as war and peace, the environment, and social justice.
For example, if followers in both traditions believe that war and chaos are necessary to usher in end times, why would they work for peace between nations? This is an important question for those participating in interfaith dialogue around the globe but takes on an especially important significance in current US-Iran relations.
The Shi'ia emphasis on the return of Imam Madhi has led some in the West, and specifically in the United States, to speculate that Iran's government may be attempting to bring about war to hasten the Mahdi's appearance. Of course, such speculations are antithetical to the teachings of Mahdism which emphasize justice and equity for all of mankind.
