when did the practice of giving up something for lent begin
Lent For other Latin Catholics, by the early 20th century the theoretical obligation of the penitential fast throughout Lent except on Sundays was to take only one full meal a day. In addition, a smaller meal, called a collation, was allowed in the evening, and a cup of some beverage, accompanied by a little bread, in the morning. In practice, this obligation, which was a matter of custom rather than of written law, was not observed strictly.[49] The 1917 Code of Canon Law allowed the full meal on a fasting day to be taken at any hour and to be supplemented by two collations, with the quantity and the quality of the food to be determined by local custom. The Lenten fast ended on Holy Saturday at noon. Only those aged 21 to 59 were obliged to fast. As with all merely ecclesiastical laws, particular difficulties, such as strenuous work or illness, excused one from observance, and a dispensation from the law could be granted by a bishop or parish priest. In addition to fasting, abstinence from meat was to be observed on Ash Wednesday and on Fridays and Saturdays in Lent.[50] A rule of thumb is that the two collations should not add up to the equivalent of another full meal. Rather portions were to be: "sufficient to sustain strength, but not sufficient to satisfy hunger".[51] The apostolic constitution Paenitemini of 17 February 1966 reduced the fasting days to two: Ash Wednesday and Good Friday, and allowed episcopal conferences to "substitute abstinence and fast wholly or in part with other forms of penitence and especially works of charity and the exercises of piety".[52] This was made part of the 1983 Code of Canon Law, which made obligatory fasting for those aged between 18 and 59, and abstinence for those aged 14 and upward.[53] The Irish Catholic Bishops' Conference decided to allow other forms of Friday penance to replace that of abstinence from meat, whether in Lent or outside Lent, suggesting alternatives such as abstaining from some other food, or from alcohol or smoking; making a special effort at participating in family prayer or in Mass; making the Stations of the Cross; or helping the poor, sick, old, or lonely.[54] The Catholic Bishops' Conference of England and Wales made a similar ruling in 1985[55] but decided in 2011 to restore the traditional year-round Friday abstinence from meat.[56] The United States Conference of Catholic Bishops has maintained the rule of abstention from meat on Friday only during Lent.[57]
Priesthood (Ancient Israel) The priests were to officiate at many offerings under the Law of Moses, including the passover sacrifice, sin offering, guilt offering, release of the scapegoat, burnt offering, peace offering, heave offering, meal offering, dough offering, drink offering, incense offering, thank offering, etc., throughout the liturgical year. As well, they would engage in many different rituals, such as the priestly blessing, the red heifer, the redemption of the firstborn, and various purification rituals.
