Augustine believed that an early abortion is not murder because, according to the Aristotelian concept of delayed ensoulment, the soul of a fetus at an early stage is not present, a belief that passed into canon law.[23][24] Nonetheless, he harshly condemned the procedure: "Sometimes, indeed, this lustful cruelty, or if you please, cruel lust, resorts to such extravagant methods as to use poisonous drugs to secure barrenness; or else, if unsuccessful in this, to destroy the conceived seed by some means previous to birth, preferring that its offspring should rather perish than receive vitality; or if it was advancing to life within the womb, should be slain before it was born."(De Nube et Concupiscentia 1.17 (15))
Thomas Aquinas, Pope Innocent III, and Pope Gregory XIV also believed that a fetus does not have a soul until "quickening," or when the fetus begins to kick and move, and therefore early abortion was not murder, though later abortion was.[10][23][not in citation given] Aquinas held that abortion was still wrong, even when not murder, regardless of when the soul entered the body.[60] Pope Stephen V and Pope Sixtus V opposed abortion at any stage of pregnancy.[23][24] https://en.wikipedia.org/wiki/History_of_Christian_thought_on_abortion#Early_Christianity
PIP: This article traces the history of the abortion policy of the Roman Catholic Church. The introductory section notes that the Church has consistently opposed abortion as evidence of sexual sin but has not always regarded it as homicide because Church teaching has never been definitive about the nature of the fetus. In addition, the prohibition of abortion has never been declared an infallible teaching. The chronology starts with a sketch of events in the first six Christian centuries when Christians sought ways to distinguish themselves from pagans who accepted contraception and abortion. During this period, Christians also decided that sexual pleasure was evil. Early Church leaders began the debate about when a fetus acquired a rational soul, and St. Augustine declared that abortion is not homicide but was a sin if it was intended to conceal fornication or adultery. During the period of 600-1500, illicit intercourse was deemed by the Irish Canons to be a greater sin than abortion, Church leaders considered a woman's situation when judging abortion, and abortion was listed in Church canons as homicide only when the fetus was formed. St. Thomas Aquinas declared that a fetus first has a vegetative soul, then an animal soul, and finally a rational soul when the body was developed. The next period, 1500-1750, found anyone who resorted to contraception or abortion subject to excommunication (1588), saw these rules relaxed in 1591, and banned abortion even for those who would be murdered because of a pregnancy (1679). From 1750 to the present, excommunication was the punishment for all abortions (1869). This punishment was extended to medical personnel in 1917, but the penalty had exceptions if the woman was young, ignorant, or operating under duress or fear. In 1930, therapeutic abortions were condemned, and, in 1965, abortion was condemned as the taking of life rather than as a sexual sin. By 1974, the right to life argument had taken hold and became part of a theory of a "seamless garment" representing a consistent ethic of life. The current Pope recognizes that the moment of ensoulment is unknown but condemns abortion in all cases (except as the unintentional byproduct of another medical procedure).Conscience. 1996 Autumn;17(3):2-5.

Sincerely. If even one person reads your info. and is curious about it, it would be worth the effort.
In fact, Catholic teaching all the way back to the Didache (late first century) correctly identifies abortion as a violation of the commandment "Thou shalt not kill," later debates about ensoulment notwithstanding.
