But I say to the unmarried, and to the widows: It is good for them if they so continue, even as I. But if they do not contain themselves, let them marry. For it is better to marry than to be burnt.
Maybe this quote from apostle Paul, when read carefully, could help you.
To the unmarried there are only two chances if they are afflicted by lust... either marriage or being burned in passions (i.e. trying resisting them). Paul doesn't even offer the third chance of premarital sex: if you can resist your passions, then do it... if you can't, then marry. The only half way is sin.
I know it is difficult to admit. I'm 25, so I can understand how HARD it is to pass through these passions and resist them - especially since I'm not engaged in a relationship and I'm afraid I won't marry soon. Yet, I know that I prefer to compromise my life and resist my passions then violating my chastity. That's frustrating, and sometimes I realise it sounds extremely odd in the world surrounding me – consider the thoughts of girls when they know my personal convictions on sex. But I'm dedicating this to God. That's enough for me.
Maybe you should keep in mind that neither Orthodoxy nor Catholicism take sex as sinful or impure. On the contrary, sex is so sacred that it shouldn't be wasted in a profane context: it would be like bathing in a baptistery as if it were a swimming pool, or eating the Eucharistic bread as if it were ordinary food to feed your body and not your soul. In the same way, sex is as sacred as love is: marriage transforms the mechanical act of sex into a way one consecrates oneself to the partner. In the Old Testament times, when the grace of Christ hadn't spread over the Church yet, sex was more or less like in our modern society... a thing to be enjoyed per se. But it is clear that this was not God's plan, as God "made them male and female" and "the husband shall leave his father and unite with his wife, and they shall become one flesh". Sexuality in a couple is the same as the fruit for a plant... it's a vital part of matrimony, that which perpetrates the love of husband and wife and transforms it into a new life. How could a Christian not to choose to consecrate this act of love to the God who gave sexuality as a means to spread life, the greatest miracle in all creation?
Also, God created life for a purpose, and just saying "God gave us sex, let's enjoy it" is wrong. God gave us sex for a purpose, and He also gave us the instructions for a correct use of it. If your father gives you a car as a present, being you the new owner, do you think you're pleasing him if you make an illegal race in town and kill someone? No, that's not the purpose while your father gave you that car... He gave it to grant you a way to move in this world – maybe to go at work and back home. So it is for sex. God gave sex for a purpose, which is the edification of a family where love can be transformed into a new life. Everytime we violate this specific function of human sexuality, we betray God who gave us this gift.
All things are lawful to me, but all things are not expedient. All things are lawful to me, but I will not be brought under the power of any. Meat for the belly, and the belly for the meats; but God shall destroy both it and them: but the body is not for fornication, but for the Lord, and the Lord for the body
Or know you not, that your members are the temple of the Holy Ghost, who is in you, whom you have from God; and you are not your own? For you are bought with a great price. Glorify and bear God in your body.
As for drugs, my personal opinion is that drug addiction is as wrong and detrimental as every other vice.
We must always bear in mind what was meant by God's instructions to "be sober" (as was discussed in the wine advice page). Drug abuse, like alcohol abuse, is nothing to play with, and Scripture very clearly warns about the dangers of excess. Excess in food or drink can cause terrible damage to your life and your soul. We should also keep in mind that some of the plants God gave us have evolved into deadly or extremely addictive substances. Some carry potential legal consequences also.
While I could spoke in favour of marijuana (I know many would be contrary to my opinion, but I know of many people who smoke marijuana without any specific addiction), I feel contrary to every other drug, even to tobacco, who give a true addiction (a smoker can't resist without cigarettes!). This is exactly in the same spirit as the citation of st. Paul I just quoted and the recommandations you extract from the Bible. Almost all drugs give addiction. You can't moderate them... it's a physical need which could burn your limbs to consumption, in a certain sense. If you find some other drug but marijuana which can't be addictive, I'll be pleased to know it, thanks.
Anyway, if you were attracted by the Orthodox Church, you must know that the Orthodox lifestyle is one of sacrifices – it is dedicating your life to God, entirely, independently that you live your faith in marriage or in celibacy... it is like transforming yourself into a living sacrament. Though I've stepped back from Orthodoxy to Roman Catholicism for dogmatic reasons alone (reasons which, anyway, live me with a great love for the Orthodox religion and all of its members!), I have interiorized the Orthodox mindset on ethics and I can assure you that I live my faith better then ever. If you have temptations, Orthodoxy is the best school to learn and resist them.
May God guide your path to salvation, as he did when he saved you from your godlessness (as I read in your biography on the webpage). Glory to God in the highest!
In Christ, Alex
PS: if you don't believe in the traditions of men, you know what? EVERYTHING in the Bible comes from men, even the passages you base or list of beliefs on. Since you just can't "pick and choose" what you believe is inspired within a text (you don't have any critical instrument to do that), you have only the choices to reject them entirely or to embrace them in fullness. The choice is yours!
