CCC 2258

"Human life is sacred because from its beginning it involves the creative action of God and it remains for ever in a special relationship with the Creator, who is its sole end. God alone is the Lord of life from its beginning until its end: no one can under any circumstance claim for himself the right directly to destroy an innocent human being."⁵⁶ CDFCDF — Congregation for the Doctrine of the Faith, instruction, Donum vitae, intro. 5.
