Euthanasia a rejection of God
In Christian teaching, suffering, especially suffering during the last moments of life, has a special place in God’s saving plan; it is in fact a sharing in Christ’s passion.
Intentionally causing one’s own death, or suicide, is murder because it is a rejection of God’s sovereignty and loving plan. It is a refusal of love for self, the denial of a natural instinct to live, a flight from the duties of justice and charity owed to one’s neighbour, to communities or to the whole of society.
