<P> In the early sixteenth century, Bishop Matteo Giberti ordered that, in his diocese of Verona, in Italy, the container case for the consecrated bread should be placed on an altar . The custom spread through northern Italy . Saint Charles Borromeo, who became Archbishop of Milan, Italy in 1560, had the Sacrament moved from the sacristy to an altar (not the main altar) of his cathedral . The edition of the Roman Missal revised and promulgated by Pope Pius V in 1570 (see Tridentine Mass) still did not envisage placing the tabernacle on an altar: it laid down instead that the altar card containing some of the principal prayers of the Mass should rest against a cross placed midway on the altar (Rubricae generales Missalis, XX - De Praeparatione Altaris, et Ornamentorum eius). However, in 1614 Pope Paul V imposed on the churches of his diocese of Rome the rule of putting the tabernacle on some altar . Reaction to Protestantism's denial of the reality and permanence of the Real Presence of Christ in the Eucharist then led to the spread of the placing of the tabernacle even on the high altar, so as to make it more evidently visible . Whether on the main altar of the church or in a special chapel, the tabernacle became more and more large and ornate, to the extent of dominating the altar . </P> <P> The Catholic Church holds the doctrine of transubstantiation, i.e. that Christ is "truly present, Body and Blood, Soul and Divinity," though under the appearance of bread or wine . This presence perdures after the consecration, so that even after Mass is concluded, the Eucharistic elements are still Christ's Body and Blood . A tabernacle serves as a secure place in which to store the Blessed Sacrament for carrying to the sick who cannot participate in Mass, or as a focus for the prayers of those who visit the church . </P> <P> The renewal of the Roman - rite liturgy following the Second Vatican Council (see Mass of Paul VI) was to highlight the primacy of the Eucharistic celebration itself, more than just a means for providing the permanent Eucharistic presence . The altar, it was decided, should be "truly the centre to which the attention of the whole congregation of the faithful naturally turns". Before Vatican II, Mass was often celebrated directly in front of the tabernacle . Today, most often, the altar for the celebration of Mass stands on its own, and the tabernacle is given its own, usually smaller, altar or it stands nearby on a pedestal or in its own separate chapel . This allows the faithful to focus on the celebration of the Eucharistic action during Mass, but preserves a dignity of place and fosters prayer and meditation outside of Mass by giving the tabernacle its own space . </P> <P> The same Instruction lays down that: </P>
