• Advent - a season observed in many Western Christian churches, a time of expectant waiting and preparation for the celebration of the Nativity of Jesus at Christmas.
• Almah – a young woman of childbearing age.
• Amen – used in Jewish, Christian and Muslim worship as a concluding word or response to prayers.
• Ancient of Days - name for God in the Book of Daniel: Atik Yomin; in the Greek Septuagint: Palaios Hemeron; and in the Vulgate: Antiquus Dierum.
• Anno Domini - Latin term for Year of the Lord, the Lord in this case being Jesus, by Christian reckoning, the Messiah. Due to western dominance of the world, this has become the common world calendar system, though many cultures separately maintain their own calendars based on various events. Recently, the terms Common Era and Anno Mundi have come into use.
• Anointing - ritual act of pouring aromatic oil over a person's head or entire body. By extension, the term is also applied to related acts of sprinkling, dousing, or smearing a person or object with any perfumed oil, milk, butter, or other fat.
• Antichrist - in Christian eschatology, the Antichrist or anti-Christ is someone recognized as fulfilling the Biblical prophecies about one who will oppose Christ and substitute himself in Christ's place.
• Antilegomena - an epithet used by the Church Fathers to denote those books of the New Testament which, although sometimes publicly read in the churches, were not — for a considerable amount of time — considered to be genuine, or received into the canon of Scripture. They were thus contrasted with the "Homologoumena", or universally acknowledged writings
• Antinomianism - in theology, is the idea that members of a particular religious group are under no obligation to obey the laws of ethics or morality, and that salvation is by predestination only
• Apocalypse - any prophetic revelation or so-called End Time scenario, or to the end of the world in general
• Apostasy - is a term generally employed to describe the formal abandonment or renunciation of one's religion, especially if the motive is deemed unworthy. In a technical sense, as used sometimes by sociologists without the pejorative connotations of the word, the term refers to renunciation and criticism of, or opposition to, one's former religion
• Apostle - were, according to the Synoptic Gospels and Christian tradition, disciples whom Jesus of Nazareth had chosen, named, and trained in order to send them on a specific mission.
• Apostolic Age - traditionally the period of the Twelve Apostles, dating from the Crucifixion of Jesus and the Great Commission until the death of John the Apostle

• Ascension of Jesus - a Christian doctrine that says Jesus ascended to heaven in the presence of his Eleven Apostles following his resurrection, and that in heaven he sits at the right hand of God the Father
• Atonement - a doctrine found within both Christianity and Judaism. It describes how sin can be forgiven by God. In Judaism, Atonement is said to be the process of forgiving or pardoning a transgression. This was originally accomplished through rituals performed by a High Priest on the holiest day of the Jewish year: Yom Kippur. In Christian theology the atonement refers to the forgiving or pardoning of sin through the crucifixion of Jesus Christ which made possible the reconciliation between God and man. Within Christianity there are numerous technical theories for how such atonement might work, including the ransom theory, the Abelardian theory, the substitutionary atonement theory with its variations, and the Anselmian satisfaction theory.

• Remez/Allegory - is a figurative mode of representation conveying a meaning other than the literal. Generally treated as a figure of rhetoric, but an allegory does not have to be expressed in language: it may be addressed to the eye, and is often found in realistic painting, sculpture or some other form of mimetic, or representative art. In allegorical representations, relationships between elements of a text or composition are understood to stand for different relationships between elements not found in the text or composition; meaning is thus constituted through the difference between the superficial meaning of the text or composition, and a "deeper" meaning. In Jewish thought this method is best known through the works of Philo. The extreme form of remez, sod, understands the Tanakh as an allegory for a mystical understanding of the universe and as a means for mystical communion with God; this approach is best known through Kabbalistic texts such as the Zohar. Traditionally, only Jews who have mastered the midrashic method and the corpus of halakha are encouraged to pursue this form of interpretation. In Christianity this method was first promoted by Saint Paul.
