Faith is confidence or trust in a person, thing, or concept. In the context of religion, faith is "belief in God or in the doctrines or teachings of religion". According to Merriam-Webster's Dictionary, faith has multiple definitions, including "something that is believed especially with strong conviction," "complete trust", "belief and trust in and loyalty to God", as well as "a firm belief in something for which there is no proof".
Natural theology, once also termed physico-theology, is a type of theology that seeks to provide arguments for theological topics based on reason and the discoveries of science, the project of arguing for the existence of God on the basis of observed natural facts, and through natural phenomena viewed as divine, or complexities of nature seen as evidence of a divine plan or Will of God, which includes nature itself.
Philosophy of religion is "the philosophical examination of the central themes and concepts involved in religious traditions". Philosophical discussions on such topics date from ancient times, and appear in the earliest known texts concerning philosophy. The field is related to many other branches of philosophy, including metaphysics, epistemology, logic and ethics.
Theism is broadly defined as the belief in the existence of at least one deity. In common parlance, or when contrasted with deism, the term often describes the classical conception of God that is found in monotheism —or gods found in polytheistic religions—or a belief in God or gods without the rejection of revelation as is characteristic of deism.
Alvin Carl Plantinga is an American analytic philosopher who works primarily in the fields of philosophy of religion, epistemology, and logic.
Christian philosophy includes all philosophy carried out by Christians, or in relation to the religion of Christianity. Christian philosophy emerged with the aim of reconciling science and faith, starting from natural rational explanations with the help of Christian revelation. Several thinkers such as Origen of Alexandria and Augustine believed that there was a harmonious relationship between science and faith, others such as Tertullian claimed that there was contradiction and others tried to differentiate them.
Apologetics is the religious discipline of defending religious doctrines through systematic argumentation and discourse. Early Christian writers who defended their beliefs against critics and recommended their faith to outsiders were called Christian apologists. In 21st-century usage, apologetics is often identified with debates over religion and theology.

Tillich taught at German universities before immigrating to the United States in 1933, where he taught at Union Theological Seminary, Harvard University, and the University of Chicago.
The existence of God is a subject of debate in theology, philosophy of religion and popular culture. A wide variety of arguments for and against the existence of God or deities can be categorized as logical, empirical, metaphysical, subjective or scientific. In philosophical terms, the question of the existence of God or deities involves the disciplines of epistemology and ontology and the theory of value.
In the philosophy of religion, Reformed epistemology is a school of philosophical thought concerning the nature of knowledge (epistemology) as it applies to religious beliefs. The central proposition of Reformed epistemology is that beliefs can be justified by more than evidence alone, contrary to the positions of evidentialism, which argues that while non-evidential belief may be beneficial, it violates some epistemic duty. Central to Reformed epistemology is the proposition that belief in God may be "properly basic" and not need to be inferred from other truths to be rationally warranted. William Lane Craig describes Reformed epistemology as "One of the most significant developments in contemporary religious epistemology ... which directly assaults the evidentialist construal of rationality."
Agnostic theism, agnostotheism, or agnostitheism is the philosophical view that encompasses both theism and agnosticism. An agnostic theist believes in the existence of one or more gods, but regards the basis of this proposition as unknown or inherently unknowable. The agnostic theist may also or alternatively be agnostic regarding the properties of the god or gods that they believe in.
Philosophical theology is both a branch and form of theology in which philosophical methods are used in developing or analyzing theological concepts. It therefore includes natural theology as well as philosophical treatments of orthodox and heterodox theology. Philosophical theology is also closely related to the philosophy of religion.
Keith Ward is an English philosopher and theologian. He is a fellow of the British Academy and a priest of the Church of England. He was a canon of Christ Church, Oxford, until 2003. Comparative theology and the relationship between science and religion are two of his main topics of interest.
In monotheistic belief systems, God is usually viewed as the supreme being, creator, and principal object of faith. In polytheistic belief systems, a god is "a spirit or being believed to have created, or for controlling some part of the universe or life, for which such a deity is often worshipped". Belief in the existence of at least one god is called theism.
Brian Leftow is an American philosopher specializing in philosophy of religion, medieval philosophy, and metaphysics. He is the William P. Alston Professor for the Philosophy of Religion at Rutgers University. Previously, he held the Nolloth Chair of the Philosophy of the Christian Religion at Oriel College, Oxford, succeeding Richard Swinburne.
Philosophical theism is the belief that the Supreme Being exists independent of the teaching or revelation of any particular religion. It represents belief in God entirely without doctrine, except for that which can be discerned by reason and the contemplation of natural laws. Some philosophical theists are persuaded of God's existence by philosophical arguments, while others consider themselves to have a religious faith that need not be, or could not be, supported by rational argument.

Is There a God? is a 1996 book by British philosopher of religion Richard Swinburne, claiming the existence of the Abrahamic God. The argument rests on an updated version of natural theology with biological evolution and Big Bang theory using scientific inference. In 2010, a revised version of the original book was released under the same title.
