In England, Presbyterianism was established in secret in 1592. Thomas Cartwright is thought to be the first Presbyterian in England. Cartwright's controversial lectures at Cambridge University condemning the episcopal hierarchy of the Elizabethan Church led to his deprivation of his post by Archbishop John Whitgift and his emigration abroad. Between 1645 and 1648, a series of ordinances of the Long Parliament established Presbyterianism as the polity of the Church of England. Presbyterian government was established in London and Lancashire and in a few other places in England, although Presbyterian hostility to the execution of Charles I and the establishment of the republican Commonwealth of England meant that Parliament never enforced the Presbyterian system in England. The re-establishment of the monarchy in 1660 brought the return of Episcopal church government in England (and in Scotland for a short time); but the Presbyterian church in England continued in Non-Conformity, outside of the established church. In 1719 a major split, the Salter's Hall controversy, occurred; with the majority siding with nontrinitarian views. Thomas Bradbury published several sermons bearing on the controversy, and in 1719, "An answer to the reproaches cast on the dissenting ministers who subscribed their belief of the Eternal Trinity.". By the 18th century many English Presbyterian congregations had become Unitarian in doctrine.

In what year did Salter's Hall controversy, occur that would lead to a split?
Answer: 1719

Armenia established a Church that still exists independently of both the Catholic and the Eastern Orthodox churches, having become so in 451 AD as a result of its stance regarding the Council of Chalcedon. Today this church is known as the Armenian Apostolic Church, which is a part of the Oriental Orthodox communion, not to be confused with the Eastern Orthodox communion. During its later political eclipses, Armenia depended on the church to preserve and protect its unique identity. The original location of the Armenian Catholicosate is Echmiadzin. However, the continuous upheavals, which characterized the political scenes of Armenia, made the political power move to safer places. The Church center moved as well to different locations together with the political authority. Therefore, it eventually moved to Cilicia as the Holy See of Cilicia.

What type of Catholicism is Armenia's church part of?
Answer: Oriental Orthodox

While Knickebein was used by German crews en masse, X-Gerat use was limited to specially trained pathfinder crews. Special receivers were mounted in He 111s, with a radio mast on the bomber's fuselage. The system worked on a higher frequency (6677 MHz, compared to Knickebein's 3033 MHz). Transmitters on the ground sent pulses at a rate of 180 per minute. X-Gerat received and analysed the pulses, giving the pilot both visual and aural "on course" signals. Three beams intersected the beam along the He 111's flight path. The first cross-beam acted as a warning for the bomb-aimer to start the bombing-clock which he would activate only when the second cross-beam was reached. When the third cross-beam was reached the bomb aimer activated a third trigger, which stopped the first hand of the equipment's clock, with the second hand continuing. When the second hand re-aligned with the first, the bombs were released. The clock's timing mechanism was co-ordinated with the distances of the intersecting beams from the target so the target was directly below when the bomb release occurred.

When the bomber crossed the first beam the bomber-aimer did what?
Answer:
start the bombing-clock
