Context and question: Ruling elders are usually laymen (and laywomen in some denominations) who are elected by the congregation and ordained to serve with the teaching elders, assuming responsibility for nurture and leadership of the congregation. Often, especially in larger congregations, the elders delegate the practicalities of buildings, finance, and temporal ministry to the needy in the congregation to a distinct group of officers (sometimes called deacons, which are ordained in some denominations). This group may variously be known as a "Deacon Board", "Board of Deacons" "Diaconate", or "Deacons' Court". These are sometimes known as "presbyters" to the full congregation.
Especially in small congregations, elders are known to delegate what?
Answer: unanswerable
Context and question: Neptune is not visible to the unaided eye and is the only planet in the Solar System found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of Uranus led Alexis Bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. Neptune was subsequently observed with a telescope on 23 September 1846 by Johann Galle within a degree of the position predicted by Urbain Le Verrier. Its largest moon, Triton, was discovered shortly thereafter, though none of the planet's remaining known 14 moons were located telescopically until the 20th century. The planet's distance from Earth gives it a very small apparent size, making it challenging to study with Earth-based telescopes. Neptune was visited by Voyager 2, when it flew by the planet on 25 August 1989. The advent of Hubble Space Telescope and large ground-based telescopes with adaptive optics has recently allowed for additional detailed observations from afar.
