Health care professionals always must "promote the dignity and life of each person and reject any compromise in the direction of euthanasia, assisted suicide or suppression of life, even in the case of terminal illness," Pope Francis has said.

"Life is sacred and belongs to God, hence it is inviolable, and no one can claim the right to dispose of it freely," the Pope said.

Pope Francis addressed health care professionals in his annual message for the celebration of World Day of the Sick, which is marked on February 11, the feast of Our Lady of Lourdes.
