A Speakers' Corner is an area where open-air public speaking, debate, and discussion are allowed. The original and most noted is in the north-east corner of Hyde Park in London, England. Speakers here may talk on any subject, as long as the police consider their speeches lawful, although this right is not restricted to Speakers' Corner only. Contrary to popular belief, there is no immunity from the law, nor are any subjects proscribed, but in practice the police intervene only when they receive a complaint. Speakers' Corner is often held up to demonstrate freedom of speech, as anyone can turn up unannounced and talk on almost any subject, although always at the risk of being heckled by regulars.

The Christian doctrine of the Trinity (Latin: trinus "threefold") holds that God is one God, but three coeternal consubstantial persons or hypostases. These being the Father, the Son (Jesus Christ), and the Holy Spirit - as "one God in three Divine Persons". The three Persons are distinct, yet are one "substance, essence or nature" (homoousios).
