Remember, you can find the full text of the General Instruction of the Roman Missal at the USCCB site. We get a reminder about the real presence of Christ in today’s section.
3. Moreover, the wondrous mystery of the real presence of the Lord under the Eucharistic species, confirmed by the Second Vatican Council and other teachings of the Church’s Magisterium in the same sense and with the same doctrine as the Council of Trent proposed that it must be believed, is proclaimed in the celebration of the Mass, not only by the very words of consecration by which Christ is rendered present through transubstantiation, but also with a sense and a demonstration of the greatest reverence and adoration which strives for realization in the Eucharistic liturgy. For the same reason, the Christian people are led to worship this wondrous Sacrament through adoration in a special way on Thursday of the Lord’s Supper in Holy Week and on the Solemnity of the Most Holy Body and Blood of Christ.
It’s important to realize that the actions and attitudes of people–laity and clergy both–preach real presence.
