Unitarianism is a religious movement that emphasizes the oneness of God and rejects the traditional Christian doctrine of the Trinity, which includes God the Father, God the Son, and God the Holy Spirit. It promotes the idea that God is a single entity rather than a triune being, and encourages individual exploration of faith and spirituality. Unitarianism also values reason, compassion, and social justice, often advocating for human rights and equality. It draws from various religious traditions, including Christianity, Buddhism, and Judaism, allowing for a diverse range of beliefs and practices among its followers.
