Your whole life decisions should be based on the advice of your priest... not only that...
And I disagree with you on NFP... that is the catholic look upon it....
NFP is and can be used as contraception... to avoid pregnancy as well as abstinece...
they are both contraception since they avoid conception..never mind the technicalities... it is stil avoiding parenthood... if does not justify using it...
Actually IMO it is more sinful to deny yourself to your spouse for avoiding conception... One has to search the fathers more to see what they say about marital relations and procreation it is only Augustine that declares that "marriage without children is sinfull" and he is quite heretical in his saying so... like if a couple is inferile their union is not blessed by God....
St Johns Homily 19 on 1 Corinthians 6 deals with the role of sexual relations in marriage. He emphasizes first of all the equality of husband and wife in this regard. Neither spouse should seek to abstain from sex without the consent of the other, and even then only temporarily. Such abstinence creates tensions in the home and often leads to adultery and divorce. St. John seems to be addressing some women in particular who have thought that they were practicing a righteous asceticism in abstaining from sex.....
Also according to St. Clement's logic or "the sperm never be waisted" then abstinence that would eventually would result in a nocturnal emission would be considered "waste" and it is not allowed....
here:
In A.D. 191 St. Clement of Alexandria (a Greek theologian of considerable influence on the theological development of the early Church) referred to Onan's evil act in these words: "He broke the law of coitus." 13 He went on to explain that "Because of its divine institution for the propagation of man, the seed is not to be vainly [bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse], nor is it to be damaged, nor is it to be wasted." 14
this specific part is about withdrawl that was used as a contraception back then ...
and also:
St. john Chrysostome":
What then? Do you condemn the gift of God and fight with his [natural] laws?... Yet such turpitude... the matter still seems indifferent to many men; even to many men having wives. In this indifference of the married men there is greater evil filth; for then poisons are prepared, not against the womb of a prostitute, but against your injured wife. Against her are these innumerable tricks". 18
[FONT=Arial, Helvetica, sans-serif]"The procreation of children in marriage is the 'heritage' and 'reward' of the Lord; a blessing of God (cf. Psalm 127:3). It is the natural result of the act of sexual intercourse in marriage, which is a sacred union through which God Himself joins the two together into 'one flesh' (Genesis 1-2, Matthew 19, Mark 10, Ephesians 5, et. al.). The procreation of children is not in itself the sole purpose of marriage, but a marriage without the desire for children, and the prayer to God to bear and nurture them, is contrary to the 'sacrament of love.'" 19[/FONT]

this from the same sit e about the Russian Church.....
A modified version of this view was also endorsed in August, 2000 at the Jubilee Bishop's Council of the Russian Orthodox Church, to whit: "Among the problems which need a religious and moral assessment is that of contraception. Some contraceptives have an abortive effect, interrupting artificially the life of the embryo on the very first stages of his life. Therefore, the same judgments are applicable to the use of them as to abortion.But other means, which do not involve interrupting an already conceived life, cannot be equated with abortion in the least."5

Thus, while it is clear that the Russian Orthodox Church allows contraception, it bans the use of those which are abortifacient, and which may have a primary or secondary effect of [/FONT]
