Oration in the context of "London Naval Treaty"

Demosthenes (/dɪˈmɒs.θəniːz/; Greek: Δημοσθένης, romanized: Dēmosthénēs; Attic Greek: [dɛːmostʰénɛːs]; 384 – 12 October 322 BC) was a Greek statesman and orator in ancient Athens. His orations constitute a significant expression of contemporary Athenian intellectual prowess and provide insight into the politics and culture of ancient Greece during the 4th century BC. Demosthenes learned rhetoric by studying the speeches of previous great orators. He delivered his first judicial speeches at the age of 20, in which he successfully argued that he should gain from his guardians what was left of his inheritance. For a time, Demosthenes made his living as a professional speechwriter (logographer) and a lawyer, writing speeches for use in private legal suits.

Demosthenes grew interested in politics during his time as a logographer, and in 354 BC he gave his first public political speeches. He went on to devote his most productive years to opposing Macedon's expansion. He idealized his city and strove throughout his life to restore Athens's supremacy and motivate his compatriots against Philip II of Macedon. He sought to preserve his city's freedom and to establish an alliance against Macedon, in an unsuccessful attempt to impede Philip's plans to expand his influence southward, conquering the Greek states.

A sermon is a religious discourse or oration by a preacher, usually a member of clergy. Sermons address a scriptural, theological, or moral topic, usually expounding on a type of belief, law, or behavior within both past and present contexts. Elements of the sermon often include exposition, exhortation, and practical application. The act of delivering a sermon is called preaching. In secular usage, the word sermon may refer, often disparagingly, to a lecture on morals.

In Christian practice, a sermon is usually preached to a congregation in a place of worship, either from an elevated architectural feature, known as a pulpit or an ambo, or from behind a lectern. The word sermon comes from a Middle English word which was derived from Old French, which in turn originates from the Latin word sermō meaning 'discourse.' A sermonette is a short sermon (usually associated with television broadcasting, as stations would present a sermonette before signing off for the night). The Christian Bible contains many speeches without interlocution, which some take to be sermons: Jesus' Sermon on the Mount in Matthew 5–7 (though the gospel writers do not specifically call it a sermon; the popular descriptor for Jesus' speech there came much later); and Peter after Pentecost in Acts 2:14–40 (though this speech was delivered to non-Christians and as such is not quite parallel to the popular definition of a sermon).

Acacius of Caesarea (Greek: Ἀκάκιος; date of birth unknown, died in 366) was a Christian bishop probably originating from Syria; Acacius was the pupil and biographer of Eusebius and his successor on the see of Caesarea Palestina. Acacius is remembered chiefly for his bitter opposition to Cyril of Jerusalem and for the part he was afterwards enabled to play in the more acute stages of the Arian controversy. The Acacian theological movement is named after him. In the twenty-first oration of St. Gregory Nazianzen, the author speaks of Acacius as being "the tongue of the Arians".

The consolatio or consolatory oration is a type of ceremonial oratory, typically used rhetorically to comfort mourners at funerals. It was one of the most popular classical rhetoric topics, and received new impetus under Renaissance humanism.
