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.

Paul the Apostle (Latin: Paulus), commonly known as Saint Paul and also known by his Jewish name Saul of Tarsus was an apostle (though not one of the Twelve Apostles) who taught the gospel of Christ to the first century world. Paul is generally considered one of the most important figures of the Apostolic Age and in the mid-30s to the mid-50s AD he founded several churches in Asia Minor and Europe. He took advantage of his status as both a Jew and a Roman citizen to minister to both Jewish and Roman audiences. According to writings in the New Testament and prior to his conversion, Paul was dedicated to persecuting the early disciples of Jesus in the area of Jerusalem. In Acts, Paul was traveling on the road from Jerusalem to Damascus on a mission to 'arrest them and bring them back to Jerusalem' when the resurrected Jesus appeared to him in a great light. He was struck blind, but after three days his sight was restored by Ananias of Damascus and Paul began to preach that Jesus of Nazareth is the Jewish Messiah and the Son of God.

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).
