The greeting of the community. A greeting of faith begins the celebration. Relatives and friends of the deceased are welcomed with a word of "consolation" (in the New Testament sense of the Holy Spirit's power in hope). The community assembling in prayer also awaits the "words of eternal life." the death of a member of the community (or the anniversary of a death, or the seventh or fortieth day after death) is an event that should lead beyond the perspectives of "this world" and should draw the faithful into the true perspective of faith in the risen Christ.
