Saint Basil the Great on abortion:
"A woman who deliberately destroys a fetus is answerable for murder. And any fine distinction between its being completely formed or unformed is not admissible among us."
"Those who give potions for the destruction of a child conceived in the womb are murderers, as are those who take potions which kill the child. "
-Saint Basil the Great (A.D. 329-379)
