The Catechism in Questions & Answers

410. What do the individual Christian denominations have in common?

Binding elements in the individual Christian denominations include baptism in the name of God, the Father, the Son, and the Holy Spirit, the profession of Jesus Christ, and belief in the triune God.
Through the baptised who live their faith and profess Christ as their Lord, the church can be experienced as a fellowship of faith, hope, and love.
