Christian theology

Christian theology is the systematic study of Christian belief and practice.

It focuses on the texts of the Old and New Testaments. It also examines long-standing Christian traditions. Theologians use biblical exegesis, which is the critical interpretation of texts. They also use rational analysis and logical argument. People study theology for many different reasons. Some want to understand their own religious tenets more deeply. Others aim to compare Christianity to other religious traditions. Some theologians use their work to defend the faith against criticism. Others use theology to facilitate reforms within the church. Some use these resources to address modern societal needs.

A central concept in this study is revelation. Revelation is the process of making the divine known to humans. This can happen through active or passive communication with God. It might come directly from God or through an agent like an angel. People who experience this contact are often called prophets. Thomas Aquinas, a famous thinker from the 13th century, described two types. General revelation occurs through observing the created order. This observation can lead to conclusions about God's existence. Special revelation involves specific truths like the Trinity or the Incarnation. These truths are found in the teachings of the Scriptures. Catholics also believe in interior locution. This is a form of revelation where a person hears an inner voice.

The Bible is considered a primary source of authority. Most Christians believe the authors were inspired by the Holy Spirit. This is often called biblical inspiration. Some modern translations use the term "God-breathed" to describe this. This comes from the Greek word *theopneustos*. There are different views on how this affects the text. Some believe the Bible is inerrant. This means it is totally without error in history and science. Others believe the Bible is infallible. This means it is true regarding faith and practice. Some thinkers argue that inspiration and inerrancy are inseparable. If the source is divine, the product should not have errors.

The collection of books in the Bible is known as the canon. Different Christian traditions use different canons for the Old Testament. Protestant Old Testaments typically contain 39 books. Roman Catholic Old Testaments contain 46 books. These extra books are called the deuterocanonical books. Eastern Orthodox traditions also have different lists. For example, Slavic traditions include the book of 2 Esdras. The Georgian Orthodox Church has unique views on the book of 4 Maccabees. However, all these groups use the same 27-book New Testament canon. In the 4th century, synods like the Synod of Hippo helped establish these lists. Jerome produced the Latin Vulgate around the year 400. This version helped set the New Testament canon for many years.

Theology also explores the nature and attributes of God. In Christianity, God is the creator and preserver of the universe. God is often presented as a personal father figure. This means God is not an impersonal force. The Bible describes God as someone who speaks, hears, and loves. God is understood to have a will and a personality. He is seen as an all-powerful and benevolent being. This means God is both powerful and kind. Theologians study these characteristics to understand how God relates to humanity.

Theologians often classify God's attributes into two groups. The first group is called communicable attributes. These are qualities that human beings can also possess. The second group is called incommunicable attributes. These belong to God alone. One such attribute is aseity. This means God is so independent that He does not need anything. This is based on the idea of God's self-sufficiency. Another attribute is eternity. This means God exists beyond the limits of time. The Westminster Shorter Catechism lists many other attributes. These include wisdom, power, holiness, justice, goodness, and truth.

Christian theology is a complex field with many different branches. These include Catholic, Orthodox, and Protestant traditions. Each branch has its own way of training ministers. They also have unique ways of interpreting the Bible. Some follow the principle of *sola scriptura*. This is the idea that the Bible is the only ultimate authority. This can be more important than the authority of the Church. Because of these different views, theology remains a very active area of study. It continues to shape how people understand their faith and the world around them.
