Religious views on truth vary both between and within religions. The most universal concept of religion that holds true in every case is the inseparable nature of truth and religious belief. Each religion sees itself as the only path to truth.^{[citation needed]} Religious truth, therefore, is never relative, always absolute.

According to an online edition of Webster's Dictionary, the word Truth is most often used to mean being in accord with fact or reality, or fidelity to an original or standard.

Christian philosopher William Lane Craig notes that the Bible typically uses the words true or truth in non-philosophical senses to indicate such qualities as fidelity, moral rectitude, and reality. However, it does sometimes use the word in the philosophical sense of veracity.

Some Christians believe that other authorities are sources of doctrinal truth. Catholics believe that the Pope is infallible when pronouncing on certain, rather specific, matters of church doctrine. On the day he was crucified, Jesus said, "For this I was born and for this I came into the world, to testify to the truth. Everyone who belongs to the truth listens to my voice." John 18:37. Pilate, did not know Jesus and infamously said, "What is truth?" John 18:38. Thus, the modern Christian must resolve contradictions and determine what became obsolete and reconciled by Jesus's ministry. Knowing God is "love" and "spirit" (words used by Jesus), are contrary to many brutal images of the Old Testament LORD, but are essential to discernment and instruction.

In Christian Science, (not recognised as a Christian organization by the bulk of mainstream churches) Truth is God.

The magisterium of the Catholic Church is the church's authority or office to establish teachings. That authority is vested uniquely in the Pope and the bishops, under the premise that they are in communion with the correct and true teachings of the faith which is shown in the Catechism of the Catholic Church. Sacred scripture and sacred tradition "make up a single sacred deposit of the Word of God, which is entrusted to the Church", and the magisterium is not independent of this, since "all that it proposes for belief as being divinely revealed is derived from this single deposit of faith."

Biblical inerrancy, as formulated in the "Chicago Statement on Biblical Inerrancy", is the doctrine that the Protestant Bible "is without error or fault in all its teaching"; or, at least, that "Scripture in the original manuscripts does not affirm anything that is contrary to fact". Various interpretations have been applied, depending on the tradition. According to some interpretations of the doctrine, all of the Bible is without error, i.e., is to be taken as true, no matter what the issue. Other interpretations hold that the Bible is always true on important matters of faith, while other interpretations hold that the Bible is true but must be specifically interpreted in the context of the language, culture and time that relevant passages were written.

There is no unilateral agreement among the different denominations of Judaism concerning truth. In Orthodox Judaism, truth is the revealed word of God, as found in the Hebrew Bible, and to a lesser extent, in the words of the sages of the Talmud. For Hasidic Jews truth is also found in the pronouncements of their rebbe, or spiritual leader, who is believed to possess divine inspiration. Kotzk, a Polish Hasidic sect, was known for their obsession with truth.^{[citation needed]}
