Answer:
Today, a number of orders of knighthood continue to exist in Christian Churches, as well as in several historically Christian countries and their former territories, such as the Roman Catholic Order of the Holy Sepulchre, the Protestant Order of Saint John, as well as the English Order of the Garter, the Swedish Royal Order of the Seraphim, and the Order of St. Olav. Each of these orders has its own criteria for eligibility, but knighthood is generally granted by a head of state, monarch, or prelate to selected persons to recognise some meritorious achievement, as in the British honours system, often for service to the Church or country.
