Christian saints are individuals recognized for their holiness and virtue within the Christian faith. They are often seen as role models for believers, having lived lives of exceptional faith, charity, and devotion to God. Saints can be canonized by the Catholic Church or recognized in other Christian traditions, and they often have specific feast days dedicated to their memory. Many saints are associated with particular causes, professions, or regions, and they may be invoked in prayer for intercession. Some well-known saints include Saint Francis of Assisi, known for his love of animals and nature, and Saint Teresa of Avila, celebrated for her mystical writings and reform of the Carmelite order.
