Throughout these chapters, we have seen how the celebration of the Eucharist is not merely a ritual but the “source and summit” of Christian life, continually renewed through the rich tapestry of sacred tradition. The historical timeline of the Eucharist—from its biblical roots to its modern expressions—reminds us that the celebration of Christ’s sacrifice has always been central to the Church’s identity. The liturgical calendar, with its dynamic cycle of seasons—Advent, Christmas, Lent, Holy Week, Easter, and Ordinary Time—provides the faithful with a structured rhythm to enter more deeply into the mysteries of salvation. Whether through the solemnity of Holy Week or the joyful renewal of Easter, each season invites a specific mode of reflection and celebration, deeply grounded in Scripture and Church teaching.
