Show me anything Paul wrote that is against contraception.
Unless he explicitly wrote the only reason to have sex is to reproduce, nothing in that chapter means men and women are not allowed to use contraception during sexual intercourse. I don't see it.
Well, for starters, 1 Timothy 2:1-15 requires reproduction where biologically possible. I could go on, as there are a great many verses of the Holy Apostle Paul which condemn contraception and which were used by the early church as the basis for prohibiting it, but to do so would be to deprive you of the benefits of searching the scriptures and the canon law of the ancient church (I suggest the Eastern Orthodox compendium, the
Pedalion, (meaning Rudder, for it steers the ship of salvation) compiled by a famous monastic on Mount Athos, St. Nicodemus the Hagiorite, which is extremely thorough and unlike Roman Catholic canon law, is unchanged, featuring some canons which predate the Council of Nicaea, as well as interpretations provided by St. Nicodemus which contain scriptural references). In reading it however one should be aware that the Orthodox interpret canon law very differently than the Roman Catholics; depending on the specifics of the case, a canon can be applied with akrivia , meaning exactitude, but it can also be applied or even set aside where appropriate using the principle of oikonomia, meaning economy; the Orthodox bishop, priest or monastic hegumen is supposed to do whatever is most expedient to facilitate the spiritual health of those who have transgressed, corresponding with the Eastern Christian view of sin as a disease to be treated, vs. the forensic approach that prevails in Western churches, particularly in Calvin, Aquinas and Anselm of Canterbury.
If we do look at the Pedalion however, we will find that St. Paul’s continuation of the Old Testament prohibition against sodomy is not restricted to homosexuals, but applies to married couples as well, who can be subject to the same penances, which can be extremely severe if applied with Akrivia. In practice, I doubt in this day and age anyone would get penanced to such an extent unless what happened was an incident of rape; indeed I suspect many priests would not even penance someone who confessed to consensual unnatural relations within a marriage. Unlike in the Roman Rite of the Roman Catholic Church, and unlike some Anglican and Lutheran priests, Orthodox priests are not required to penance those who seek the Sacrament of Reconciliation, and during my very happy time in the OCA, it never happened to me, even when I confessed in theologically strict ROCOR parishes.
The Sui Juris Eastern Catholic churches have however done much to inject Eastern soteriology into the Western Rites of the Roman Catholic Church, just as dialogue with the Orthodox has had a similiar effect for high church Anglicanism (and indeed, the influence of Dr. Rowan Williams, who considered a vocation as an Orthodox priest, during his tenure as Archbishop of the Anglican Church in Wales, and later as Archbishop of Canterbury, the primus inter pares of the Church of England (which is the last state church in the Anglican Communion) and primus inter pares and presiding bishop of the Anglican Communion itself.
Referring to contraception and further scriptural condemnation of it, we have the case of Ona in Genesis, which some interpret as referring to the yielding of someone to biological temptation, but which others interpret as referring to a specific and extremely common mode of contraception in which the reproductive process is interrupted. And indeed, it could well refer to both, insofar as the former can also be used as a contraceptive alternative to natural matrimonial reproduction.
Scripture in general, and St. Paul in particular makes it clear that for those able to procreate, only procreative relations in the context of Holy Matrimony, or Holy Celibacy, are acceptable.
Note that what I have said about the Eastern Orthodox is generally applicable to Byzantine Rite Catholic Churches, except they dont use the Pedalion but the more recent Code of Canon Law of the Eastern Churches.
