Nuns and monks lived in segregated nunneries and monasteries on church land and grew their own food. The local bishop usually was also an abbot of a monastery. The priests and nuns wore long robes with loose belts and did not carry weapons. Their life was ordered by the ringing of the bell to start certain activities, such as prayer; meals; meetings; work in the fields, gardens, or workshops; and copying and illuminating books. They chanted to pay homage and to communicate with God or his saints. They taught justice, piety, chastity, peace, and charity; and cared for the sick. Caring for the sick entailed mostly praying to God as it was thought that only God could cure. They bathed a few times a year. They got their drinking water from upstream of where they had located their latrines over running water. The large monasteries had libraries, dormitories, guesthouses, kitchens, butteries to store wine, bakehouses, breweries, dairies, granaries, barns, fishponds, orchards, vineyards, gardens, workshops, laundries, lavatories with long stone or marble washing troughs, and towels. Slavery was diminished by the church by excommunication for the sale of a child over seven. The clergy taught that manumission of slaves was good for the soul of the dead, so it became frequent in wills. The clergy were to abstain from red meat and wine and were to be celibate. But there were periods of laxity. Punishment was by the cane or scourge. The Archbishop of Canterbury began anointing new kings at the time of coronation to emphasize that the king was ruler by the grace of God. As God's minister, the king could only do right. From 973, the new king swore to protect the Christian church, to prevent inequities to all subjects, and to render good justice, which became a standard oath.
