of the holy Apostles and martyrs have their own commune from Easter to Pentecost. At Mass the Alleluia is added to the Introit, Offertory and Communion; in place of the Gradual two Alleluias are sung followed by two verses, each with an Alleluia; there is also a special Preface for Paschal Time. Paschal Tide was the period during which every member of the faithful who has attained the year of discretion was bound by the positive law of the Church to receive Holy Communion (Easter duty). During the early Middle Ages from the time of the Synod of Agde (508), it was customary to receive Holy Communion at least three times a year—Christmas, Easter and Pentecost. A positive precept was issued by the Fourth Lateran Council (1215) and confirmed by the Council of Trent (Sess. XIII, can. ix). According to these decrees the faithful of either sex, after coming to the age of discretion, must receive at least at Easter the Sacrament of the Eucharist (unless by the advice of the parish priest they abstain for a while). Otherwise during life they are to be prevented from entering the church and when dead are to be denied Christian burial. The paschal precept is to be fulfilled in one's parish church. Although the precept of the Fourth Lateran to confess to the parish priest fell into disuse and permission was given to confess anywhere, the precept of receiving Easter Communion in the parish church was still in force where there are canonically-erected parishes. The term Paschal Tide was usually interpreted to mean the two weeks between Palm and Low Sundays (Synod of Avignon, 1337). By St. Antonine of Florence it was restricted to Easter Sunday, Monday and Tuesday. By Angelo da Chiavasso it was defined as the period from Maundy Thursday to Low Sunday. Eugene IV, 8 July 1440, authoritatively interpreted it to mean the two weeks between Palm and Low Sundays. In later centuries the time has been variously extended: at Naples from Palm Sunday to Ascension; at Palermo from Ash Wednesday to Low Sunday. In Germany, at an early date, the second Sunday after Easter terminated Paschal Tide, for which reason it was called "Predigerkirchweih", because the hard Easter labour was over, or "Buch Sunday", the obstinate sinners putting off the fulfillment of the precept to the last day.
