  Western Christianity displayed a remarkable unity. This was the outcome of the Gregorian Reform that established papal supremacy over the Catholic Church, and achieved the legal separation of the Catholic clergy from laity. Clerical celibacy was reinforced through the prohibition of clerical marriage; ecclesiastical courts were granted exclusive jurisdiction over clerics, and also over matrimonial causes. Priests were ordained by bishops in accordance with the principle of apostolic succession —a claim to the uninterrupted transmission of their consecrating power from Christ's Apostles through generations of bishops. Bishops, abbots, abbesses, and other prelates might possess remarkable wealth. Some of the ecclesiastic leaders were also secular princes, such as the prince-bishops in Germany and the Grand Masters of the Teutonic Knights in their Baltic Ordensstaat. Other prelates might be the power behind the throne. Believers were expected to pay the tithe (one tenth of their income) to the Church. Pluralism—the practice of holding multiple Church offices (or benefices)—was not unusual. This led to non-residence, and the absent priests' deputies were often poorly educated and underpaid.
  
  The clergy consisted of two major groups, the regular clergy and the secular clergy. Regular clerics lived under a monastic rule within the framework of a religious order; secular clerics were responsible for pastoral care. The Church was a hierarchical organisation. The pope was elected by high-ranking clergymen, the cardinals, and assisted by the professional staff of the Roman Curia. Secular clerics were organised into territorial units known as dioceses, each ruled by a bishop or archbishop. Each diocese was divided into parishes headed by parish priests who administered most sacraments to the faithful. These were sacred rites thought to transfer divine grace to humankind. The Council of Florence declared baptism, confirmation, marriage, extreme unction, penance, the Eucharist, and priestly ordination as the seven sacraments of the Catholic Church. Women were not ordained priests but could live as nuns in convents after taking the three monastic vows of poverty, chastity, and obedience.
