(Jn 6, 34-40) Not lose anything of what he gave me

[34] So they said to him, "Sir, give us this bread always." [35] Jesus said to them, "I am the bread of life; whoever comes to me will never hunger, and whoever believes in me will never thirst. [36] But I told you that although you have seen (me), you do not believe. [37] Everything that the Father gives me will come to me, and I will not reject anyone who comes to me, [38] because I came down from heaven not to do my own will but the will of the one who sent me. [39] And this is the will of the one who sent me, that I should not lose anything of what he gave me, but that I should raise it (on) the last day. [40] For this is the will of my Father, that everyone who sees the Son and believes in him may have eternal life, and I shall raise him (on) the last day."

(CCC 1409) The Eucharist is the memorial of Christ's Passover, that is, of the work of salvation accomplished by the life, death, and resurrection of Christ, a work made present by the liturgical action. (CCC 1399) The Eastern churches that are not in full communion with the Catholic Church celebrate the Eucharist with great love. "These Churches, although separated from us, yet possess true sacraments, above all - by apostolic succession - the priesthood and the Eucharist, whereby they are still joined to us in closest intimacy." A certain communion in sacris, and so in the Eucharist, "given suitable circumstances and the approval of Church authority, is not merely possible but is encouraged" (UR 15 § 2; cf. CIC, can. 844 § 3). (CCC 1400) Ecclesial communities derived from the Reformation and separated from the Catholic Church, "have not preserved the proper reality of the Eucharistic mystery in its fullness, especially because of the absence of the sacrament of Holy Orders" (UR 22 § 3). It is for this reason that Eucharistic intercommunion with these communities is not. However these ecclesial communities, "when they commemorate the Lord's death and resurrection in the Holy Supper . . . profess that it signifies life in communion with Christ and await his coming in glory" (UR 22 § 3). (CCC 1401) When, in the Ordinary's judgment, a grave necessity arises, Catholic ministers may give the sacraments of Eucharist, Penance, and Anointing of the Sick to other Christians not in full communion with the Catholic Church, who ask for them of their own will, provided they give evidence of holding the Catholic faith regarding these sacraments and possess the required dispositions (CIC, can. 844 § 4).
