Excellent point .. but, there are plenty of quotes, not necessarily from Scripture. They come from the Extra-Canonical books, like the Didache and the Early Church Fathers. The Didache is one of the earliest written documents of the Church other than Scripture itself. It was written sometime between 90 and 110 AD. It may not have had a single author but may have been compiled from the Apostolic Teaching as a kind of early catechism and a summary of the essential moral tenets of the Faith. It’s existence demonstrates that many current teachings of the faith, often under attack by modernity, are in fact very ancient, going right back to the beginning. Let’s take a look at some excerpts from the Didache that are especially pertinent for today’s controversies. Here are some examples from both:
"You shall not commit murder, you shall not commit adultery, you shall not commit pederasty, you shall not commit fornication, you shall not steal, you shall not practice magic, you shall not practice witchcraft, you shall not murder a child by abortion nor kill one that has been born"
(Didache 2:2 [A.D. 70])."[W]e have been taught that to expose newly-born children is the part of wicked men; and this we have been taught lest we should do anyone harm and lest we should sin against God, first, because we see that almost all so exposed (not only the girls, but also the males) are brought up to prostitution. And for this pollution a multitude of females and hermaphrodites, and those who commit unmentionable iniquities, are found in every nation. And you receive the hire of these, and duty and taxes from them, whom you ought to exterminate from your realm. And anyone who uses such persons, besides the godless and infamous and impure intercourse, may possibly be having intercourse with his own child, or relative, or brother. And there are some who prostitute even their own children and wives, and some are openly mutilated for the purpose of sodomy; and they refer these mysteries to the mother of the gods"
Justin Martyr - (First Apology 27 [A.D. 151])."[A]ll other frenzies of the lusts which exceed the laws of nature, and are impious toward both [human] bodies and the sexes, we banish, not only from the threshold but also from all shelter of the Church, for they are not sins so much as monstrosities"
Tertullian (Modesty 4 [A.D. 220]).
“Progressive” Christians (Catholics included) maintain that the early Church after the Ascension was simply men dictating their opinions, which have been handed down under the guise of faith, and which have no validity; to bring up anyone other than Christ Himself has no meaning to them. They are determined to create a “church” in which they can divorce, abort, and sodomize, and will completely ignore any inconvenient obstacle to this end.
