FTA: “4. In circumstances when cremation is chosen because of sanitary, economic or social considerations, this choice must never violate the explicitly-stated or the reasonably inferable wishes of the deceased faithful. The Church raises no doctrinal objections to this practice, since cremation of the deceased’s body does not affect his or her soul, nor does it prevent God, in his omnipotence, from raising up the deceased body to new life. Thus cremation, in and of itself, objectively negates neither the Christian doctrine of the soul’s immortality nor that of the resurrection of the body.The Church continues to prefer the practice of burying the bodies of the deceased, because this shows a greater esteem towards the deceased. Nevertheless, cremation is not prohibited, “unless it was chosen for reasons contrary to Christian doctrine”.In the absence of motives contrary to Christian doctrine, the Church, after the celebration of the funeral rite, accompanies the choice of cremation, providing the relevant liturgical and pastoral directives, and taking particular care to avoid every form of scandal or the appearance of religious indifferentism.”
This is NOT new. It is the official teaching of the Catholic Church and has been for a long time. To understand this teaching regarding cremation of the dead (sadly, many Catholics don’t) the sourced document from the Congregation for the Doctrine of the Faith is linked below.
