Viaticum

Time you got around to sponsoring a child
Viaticum, a Latin word originally meaning 'travelling provisions', is used in Roman Catholicism for the Eucharist (consecrated host) administered to a dying person.

(The word beaticum, sometimes found in place of viaticum, is incorrect; it has probably arisen from mishearing, or from a vague association with beatus = blessed.)
