Commemoration of All the Faithful Departed
St. Augustine: "But as for the burying of the body, whatever is bestowed on that, is no aid of salvation, but an office of humanity, according to that affection by which no man ever hates his own flesh. Whence it is fitting that he take what care he is able for the flesh of his neighbor, when he is gone that bare it. And if they do these things who believe not the resurrection of the flesh, how much more are they beholden to do the same who do believe; that so, an office of this kind bestowed upon a body, dead but yet to rise again and to remain to eternity, may also be in some sort a testimony of the SAME Faith?" (Book on the Care for the Deceased, Lesson VI, Office of Matins).
Vatican II Neo-Catholics say they are 'Catholics' because they accept what the Pope, the bishops, and the clergy 'say' - Cremation is OK; it's practical. That criterion is just a fabrication. One essential element that makes a Catholic "Catholic" is adherence to the "SAME" Faith of our Fathers (cf., "Fundamentals of Catholic Dogma" by L. Ott). But yet, the Son of Man, when He comes, shall He find, think ye, Faith on earth? (Lk. 18.8)
