Umm, no, the church has never supported abortion

Saint John Chrysostom (c. 347–407)
"Why sow where the ground makes it its care to destroy the fruit? -where there are many efforts at abortion?- where there is murder before the birth? For even the harlot you do not let continue a mere harlot, but make her a murderess also. You see how drunkenness leads to prostitution, prostitution to adultery, adultery to murder; or rather to a something even worse than murder. For I have no name to give it, since it does not take off the thing born, but prevents its being born. Why then do thou abuse the gift of God, and fight with his laws, and follow after what is a curse as if a blessing, and make the chamber of procreation a chamber for murder, and arm the woman that was given for childbearing unto slaughter?"
From his homily of Roman 24
Saint Basil the Great (329-279 AD)
"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."
I'm sure I could find some earlier quotes from great teachers and writers in the church if the 4th century is not early enough.
