Mass is the main Eucharistic liturgical service in many forms of Western Christianity. The term Mass is commonly used in the Catholic Church, Western Rite Orthodoxy, Old Catholicism, and Independent Catholicism. The term is used in some Lutheran churches, as well as in some Anglican churches. The term is also used, on rare occasion, by other Protestant churches.
A catechism is a summary or exposition of doctrine and serves as a learning introduction to the Sacraments traditionally used in catechesis, or Christian religious teaching of children and adult converts. Catechisms are doctrinal manuals – often in the form of questions followed by answers to be memorised – a format that has been used in non-religious or secular contexts as well. According to Norman DeWitt, the early Christians appropriated this practice from the Epicureans, a school whose founder Epicurus had instructed to keep summaries of the teachings for easy learning. The term catechumen refers to the designated recipient of the catechetical work or instruction. In the Catholic Church, catechumens are those who are preparing to receive the Sacrament of Baptism. Traditionally, they would be placed separately during Holy Mass from those who had been baptized, and would be dismissed from the liturgical assembly before the Profession of Faith and General Intercessions.
A mortal sin, in Catholic theology, is a gravely sinful act which can lead to damnation if a person does not repent of the sin before death. It is alternatively called deadly, grave, and serious. A sin is considered to be "mortal" when its quality is such that it leads to a separation of that person from God's saving grace. Three conditions must together be met for a sin to be mortal: "Mortal sin is sin whose object is grave matter and which is also committed with full knowledge and deliberate consent." The sin against the Holy Spirit and the sins that cry to Heaven for vengeance are considered especially serious. This type of sin is distinguished from a venial sin in that the latter simply leads to a weakening of a person's relationship with God. Despite its gravity, a person can repent of having committed a mortal sin. Such repentance is the primary requisite for forgiveness and absolution. Teaching on absolution from serious sins has varied somewhat throughout history. The current teaching for Catholics was formalized at the 16th-century Council of Trent.
In theology, Divine Providence, or simply Providence, is God's intervention in the Universe. The term Divine Providence is also used as a title of God. A distinction is usually made between "general providence", which refers to God's continuous upholding of the existence and natural order of the Universe, and "special providence", which refers to God's extraordinary intervention in the life of people. Miracles generally fall in the latter category.
Crypto-Calvinism is a pejorative term describing a segment of those members of the Lutheran Church in Germany who were accused of secretly subscribing to Calvinist doctrine of the Eucharist in the decades immediately after the death of Martin Luther in 1546. It denotes what was seen as a hidden Calvinist belief, i.e., the doctrines of John Calvin, by members of the Lutheran Church. The term crypto-Calvinist in Lutheranism was preceded by terms Zwinglian and Sacramentarian. Also, Jansenism has been accused of crypto-Calvinism by Roman Catholics.
The Book of Concord (1580) or Concordia is the historic doctrinal standard of the Lutheran Church, consisting of ten credal documents recognized as authoritative in Lutheranism since the 16th century. They are also known as the symbolical books of the Evangelical Lutheran Church.
Religions with the belief in a future judgment, a resurrection of the dead or a purgatory often offer prayers on behalf of the dead to God.
Luther's Small Catechism is a catechism written by Martin Luther and published in 1529 for the training of children. Luther's Small Catechism reviews the Ten Commandments, the Apostles' Creed, the Lord's Prayer, the Sacrament of Holy Baptism, the Office of the Keys and Confession and the Sacrament of the Eucharist. It is included in the Book of Concord as an authoritative statement of what Lutherans believe.
Confessional Lutheranism is a name used by Lutherans to designate those who believe in the doctrines taught in the Book of Concord of 1580 in their entirety. Confessional Lutherans maintain that faithfulness to the Book of Concord, which is a summary of the teachings found in Scripture, requires attention to how that faith is actually being preached, taught, and put into practice. Confessional Lutherans believe that this is a vital part of their identity as Lutherans.
The Roman Catechism or Catechism of the Council of Trent is a compendium of Catholic doctrine commissioned during the Counter-Reformation by the Council of Trent, to expound doctrine and to improve the theological understanding of the clergy. It was published in 1566.
In Protestant Christianity, the relationship between Law and Gospel—God's Law and the Gospel of Jesus Christ—is a major topic in Lutheran and Reformed theology. In these religious traditions, the distinction between the doctrines of Law, which demands obedience to God's ethical will, and Gospel, which promises the forgiveness of sins in light of the person and work of Jesus Christ, is critical. Ministers use it as a hermeneutical principle of biblical interpretation and as a guiding principle in homiletics and pastoral care. It involves the supersession of the Old Covenant by the New Covenant and Christian theology.
Catechesis is basic Christian religious education of children and adults, often from a catechism book. It started as education of converts to Christianity, but as the religion became institutionalized, catechesis was used for education of members who had been baptized as infants. As defined in the Catechism of the Catholic Church, paragraph 5 :
Catechesis is an education in the faith of children, young people and adults which includes especially the teaching of Christian doctrine imparted, generally speaking, in an organic and systematic way, with a view to initiating the hearers into the fullness of Christian life.
The Mass is the central liturgical service of the Eucharist in the Catholic Church, in which bread and wine are consecrated and become the body and blood of Christ. As defined by the Church at the Council of Trent, in the Mass "the same Christ who offered himself once in a bloody manner on the altar of the cross, is present and offered in an unbloody manner". The Church describes the Mass as the "source and summit of the Christian life", and teaches that the Mass is a sacrifice, in which the sacramental bread and wine, through consecration by an ordained priest, become the sacrificial body, blood, soul, and divinity of Christ as the sacrifice on Calvary made truly present once again on the altar. The Catholic Church permits only baptised members in the state of grace to receive Christ in the Eucharist.
The theology of Martin Luther was instrumental in influencing the Protestant Reformation, specifically topics dealing with justification by faith, the relationship between the Law and Gospel, and various other theological ideas. Although Luther never wrote a systematic theology or a "summa" in the style of St. Thomas Aquinas, many of his ideas were systematized in the Lutheran Confessions.
Martin Luther was a German priest, theologian, author, hymnwriter, professor, and Augustinian friar. He was the seminal figure of the Protestant Reformation, and his theological beliefs form the basis of Lutheranism.
Catholic theology is the understanding of Catholic doctrine or teachings, and results from the studies of theologians. It is based on canonical scripture, and sacred tradition, as interpreted authoritatively by the magisterium of the Catholic Church. This article serves as an introduction to various topics in Catholic theology, with links to where fuller coverage is found.
In the Lutheran Church, Confession is the method given by Christ to the Church by which individual men and women may receive the forgiveness of sins; according to the Large Catechism, the "third sacrament" of Holy Absolution is properly viewed as an extension of Holy Baptism.
Lutheranism is a major branch of Protestantism, identifying primarily with the theology of Martin Luther, the 16th-century German monk and reformer whose efforts to reform the theology and practice of the Catholic Church launched the Protestant Reformation.
Luther's canon is the biblical canon attributed to Martin Luther, which has influenced Protestants since the 16th-century Protestant Reformation. While the Lutheran Confessions specifically did not define a biblical canon, it is widely regarded as the canon of the Lutheran Church. It differs from the 1546 Roman Catholic canon of the Council of Trent in that it rejects the deuterocanonical books and questions the seven New Testament books, called "Luther's Antilegomena", four of which are still ordered last in German-language Luther Bibles to this day.
The Lutheran sacraments are "sacred acts of divine institution". Lutherans believe that, whenever they are properly administered by the use of the physical component commanded by God along with the divine words of institution, God is, in a way specific to each sacrament, present with the Word and physical component. They teach that God earnestly offers to all who receive the sacrament forgiveness of sins and eternal salvation. They teach that God also works in the recipients to get them to accept these blessings and to increase the assurance of their possession.
