***The Church is the universal sacrament of salvation (79), since, united always in a mysterious way to the Saviour Jesus Christ, her Head, and subordinated to him, she has, in God’s plan, an indispensable relationship with the salvation of every human being (80). ***For those who are not formally and visibly members of the Church, salvation in Christ is accessible by virtue of a grace which, while having a mysterious relationship to the Church, does not make them formally part of the Church, but enlightens them in a way which is accommodated to their spiritual and material situation. This grace comes from Christ; it is the result of his sacrifice and is communicated by the Holy Spirit (81); it has a relationship with the Church, which according to the plan of the Father, has her origin in the mission of the Son and the Holy Spirit (82).
