Christian ethics and morality form the foundation of how believers should live their lives. Rooted in biblical teachings and the example of Jesus Christ, these principles guide Christians in making moral decisions and living virtuously.

Key concepts include love, justice, and stewardship. The Ten Commandments, Jesus' teachings, and writings of early Church leaders all shape Christian ethical thought. Sin, redemption, and virtues like faith and humility are central themes.

Foundations of Christian ethics

• Christian ethics are rooted in the moral teachings found in the Old and New Testaments of the Bible, which provide guidance on how to live a virtuous life in accordance with God's will
• The life and teachings of Jesus Christ, as recorded in the Gospels, serve as the central foundation for Christian moral principles and values
• The Church Fathers, early Christian theologians and leaders (Augustin, Aquinas), played a significant role in interpreting and developing Christian ethical thought based on scriptural teachings

Old Testament moral teachings

• The Ten Commandments (Exodus 20:1-17) establish fundamental moral rules, such as prohibiting murder, theft, and adultery, and emphasizing the importance of honoring God and respecting others

Sanctity of human life

• The principle of the sanctity of human life affirms that every person is created in the image of God (Genesis 1:27) and possesses inherent worth and dignity
• This principle underlies Christian opposition to practices such as abortion, euthanasia, and the death penalty, which are seen as violations of the fundamental right to life
• Christians are called to protect and defend human life at all stages, from conception to natural death, and to promote a culture of life that values and supports the most vulnerable members of society

Stewardship and responsibility

• The principle of stewardship recognizes that all of creation, including human life and natural resources, belongs to God and is entrusted to human care and responsibility
• Christians are called to be faithful stewards of the gifts and resources God has given them, using them wisely and for the benefit of others (Matthew 25:14-30)
• This principle extends to the care of the environment, as Christians have a responsibility to protect and preserve the natural world for future generations (Genesis 2:15)

Christian virtues

• Christian virtues are moral qualities and character traits that reflect the character of Christ and enable Christians to live a life pleasing to God
• The cultivation of these virtues is essential for spiritual growth and the development of a mature Christian character

Faith, hope, and charity

• Faith, hope, and charity (love) are known as the theological virtues, as they are directly related to God and are infused into the soul by divine grace
• Faith is the belief in God and the truths revealed in Scripture, enabling Christians to trust in God's promises and live in accordance with His will
• Hope is the confident expectation of eternal life and the fulfillment of God's kingdom, providing strength and perseverance in the face of adversity
• Charity (love) is the greatest of the theological virtues (1 Corinthians 13:13), as it reflects God's unconditional love for humanity and enables Christians to love God and others selflessly

Prudence, justice, fortitude, and temperance

• Prudence, justice, fortitude, and temperance are known as the cardinal virtues, as they are considered the "hinges" (Latin: cardo) on which the moral life turns
• Prudence is the virtue of practical wisdom, enabling Christians to discern the right course of action in a given situation and to make sound moral judgments

Sin and redemption

• Sin is a central concept in Christian ethics, as it represents the human condition of separation from God and the need for redemption and salvation
• The doctrine of sin helps to explain the presence of evil and suffering in the world, and the necessity of God's grace and Christ's sacrificial death for the restoration of humanity

Nature and consequences of sin

• Sin is understood as any thought, word, or action that violates God's moral law and offends His holiness
• The consequences of sin include spiritual death (separation from God), physical death, and the corruption of human nature, leading to a tendency towards evil and the inability to perfectly obey God's law
• Sin affects not only individuals but also relationships, communities, and the entire created order, leading to social injustice, conflict, and environmental degradation

Original sin vs personal sin

• Original sin refers to the inherited sinful condition of humanity, resulting from the fall of Adam and Eve in the Garden of Eden (Genesis 3)
• This doctrine emphasizes that all people are born with a predisposition towards sin and are in need of God's saving grace
• Personal sin refers to the actual sins committed by individuals, whether in thought, word, or deed, for which they are morally responsible and accountable before God
• While original sin affects all of humanity, personal sin is the result of an individual's free choice to disobey God and violate His moral law

Role of confession and penance

• The practice of confession is based on the belief that God is merciful and willing to forgive those who sincerely repent and seek His forgiveness (1 John 1:9)
• Penance is the act of making reparation for one's sins, often through prayer, fasting, or acts of charity and service
• In the Catholic tradition, the sacrament of reconciliation (confession) involves confessing one's sins to a priest, receiving absolution, and performing an act of penance as a sign of contrition and the desire to amend one's life

Salvation through Christ

• The doctrine of salvation affirms that the forgiveness of sins and the restoration of humanity's relationship with God is made possible through the life, death, and resurrection of Jesus Christ

• By faith in Christ and His atoning work, individuals can receive the gift of salvation and be reconciled to God, experiencing new life and the transforming power of the Holy Spirit (Ephesians 2:8-9)
• The Christian life is characterized by a continual process of sanctification, as believers grow in holiness and conformity to the image of Christ through the power of the Holy Spirit and the practice of spiritual disciplines (2 Corinthians 3:18)

Christian moral decision-making

• Christian moral decision-making involves the application of biblical principles, church teachings, and personal discernment to the complex ethical challenges of daily life
• The goal of Christian moral decision-making is to discern and follow God's will, to glorify Him, and to promote the well-being of oneself and others

Conscience and discernment

• Conscience is the inner voice or moral sense that helps individuals distinguish between right and wrong, and prompts them to act in accordance with their moral convictions
• The Christian understanding of conscience emphasizes the need for its proper formation through the study of Scripture, the guidance of the Church, and the cultivation of virtues
• Discernment is the process of prayerfully seeking God's will and wisdom in a particular situation, considering the moral principles involved, the potential consequences, and the leading of the Holy Spirit
• The practice of discernment involves examining one's motives, seeking godly counsel, and being attentive to the promptings of the Holy Spirit, as exemplified in the decision-making of the early Church (Acts 15:28)

Biblical guidance and interpretation

• The Bible serves as the primary source of moral guidance for Christians, providing principles, commandments, and examples that inform ethical decision-making

• Biblical principles such as love, justice, compassion, and stewardship serve as overarching themes that guide moral discernment and action

Church teachings and authority

• The teachings of the Church, as expressed in creeds, councils, and the writings of theologians and church leaders, provide guidance and support for Christian moral decision-making
• The authority of the Church is based on its role as the Body of Christ and the guardian of the apostolic faith, entrusted with interpreting Scripture and guiding the moral life of believers
• Different Christian traditions (Catholic, Orthodox, Protestant) have varying understandings of the nature and extent of church authority in moral matters
• While church teachings are to be respected and carefully considered, individual Christians are ultimately responsible for their own moral choices and must follow their informed consciences

Personal prayer and reflection

• Personal prayer and reflection are essential components of Christian moral decision-making, as they help individuals discern God's will and gain wisdom and strength to act in accordance with their moral convictions
• Prayer involves bringing one's moral struggles, questions, and decisions before God, seeking His guidance, and surrendering to His will
• Reflection involves examining one's thoughts, motives, and actions in light of biblical principles and the promptings of the Holy Spirit, and being open to correction and growth

• Ethical discernment in bioethics involves balancing the principles of autonomy, beneficence, non-maleficence, and justice, while upholding the fundamental dignity of the human person

Sexual ethics and marriage

• Christian sexual ethics is based on the belief that human sexuality is a gift from God, designed for the purposes of procreation, intimacy, and the expression of love within the context of marriage between a man and a woman
• The Bible teaches that sexual activity outside of marriage, including premarital sex, adultery, and homosexual acts, is contrary to God's will and harmful to individuals and society (1 Corinthians 6:18-20, Hebrews 13:4)
• The Christian understanding of marriage emphasizes its sacramental nature as a lifelong, exclusive, and faithful union between husband and wife, reflecting the love and commitment of Christ to His Church (Ephesians 5:22-33)
• Contemporary challenges in sexual ethics include the prevalence of pornography, the acceptance of cohabitation and casual sexual relationships, and the debate over same-sex marriage and LGBT rights

Social justice and human rights

• The concept of eco-justice emphasizes the interconnectedness of social and environmental issues, and the need to address both in an integrated manner, promoting the well-being of both human communities and the natural world

Christian ethics vs secular ethics
