Following the slight tangent....
Hm, I know several very religious types that fully support me getting off smoking via e-cigs.
I have an example from today, in fact. My devout Evangelical Protestant friends have been very gracious regarding my smoking, never pestering me about it, but I know they were extremely opposed to me smoking. They were (I think quite rightly) concerned about my health. When I told them I'd taken up vaping and not smoked all week, they were thrilled. When I visited with them today, they wanted to see my kit and even asked me to demonstrate. I offered to do it outside, since I would never have smoked in their house, and they said, "No, go ahead. Right here. We want to see it." They're totally psyched that I've started vaping.
I did not know churches had smoking beliefs... Why?, unless they are some sort of holistic group maybe.
Just as beliefs regarding smoking vary from one religious group to another, so do reasons for opposition among those who are opposed.
Among Buddhists, for example, the traditional "Five Precepts" forbid drinking alcohol. Some Buddhists have interpreted this to forbid any intoxicant, and some of those have also interpreted it to forbid non-intoxicating but addictive substances as well. Of course, not all Buddhists think the same ways about the meaning of the five precepts-- some Buddhists drink alcohol moderately, some Buddhists smoke, etc. But the interpretation exists among some of them. Why? Sobriety, self-control, and detachment are very important values within Buddhism, making a better rebirth or even liberation easier to attain.
Among Mormons, to choose another example, the "Word of Wisdom," which Mormons believe to be a revelation of their Heavenly Father through Joseph Smith, governs their thinking regarding tobacco: "thus saith the Lord unto you: ...I have warned you, and forewarn you, by giving unto you this word of wisdom by revelation— ....tobacco is not for the body, neither for the belly, and is not good for man, but is an herb for bruises and all sick cattle, to be used with judgment and skill." As among Buddhists with the Five Precepts, Mormons differ among themselves somewhat regarding how they understand and apply the Word of Wisdom, but I think most of them would probably consider this a ban not only on tobacco smoking/chewing/etc. (the somewhat obvious interpretation) but also on other nicotine use (the prohibition of hot drinks, for example, is applied to any drink containing caffeine, no matter how cold it's served).
Among Catholics, in contrast, use of tobacco is
not forbidden. Instead,
moderation is encouraged. The "Catechism of the Catholic Church" reasons "The virtue of temperance disposes us to avoid every kind of excess: the abuse of food, alcohol, tobacco, or medicine." It's not an absolute prohibition, as above, and yet I think it expresses some shared concerns. Like Buddhists, Catholics esteem sobriety and self-control as virtues. As among Mormons, concern for health is a factor: "Life and physical health are precious gifts entrusted to us by God. We must take reasonable care of them, taking into account the needs of others and the common good," (Catechism again). This admonition falls under the broader heading "You shall not kill."
Southern Baptists have, if I am not mistaken, a very conflicted history with tobacco. Tobacco use is often condemned among Baptist preachers and their flocks, but tobacco is also a major cash crop in Southern Baptist country. The 1984 resolution of the SBC regarding cigarette smoking shows signs of that historical tension: "WHEREAS, We as Christians know that our bodies are temples of the Holy Spirit, and that we should therefore refrain from defiling our bodies.... Cigarette smoking is causally related to lung cancer and coronary heart disease, as well as other diseases, and is the leading cause of chronic bronchitis and emphysema.... Therefore, be it RESOLVED.... That we encourage parents by personal example to teach abstinence from cigarette smoking.... That our churches, associations, state conventions, and the Southern Baptist Convention take leadership in encouraging our people, pastors, and SBC leaders to refrain from using tobacco in any form, including cigarettes; and Be it further RESOLVED, That we encourage Southern Baptists presently engaged in the growing of tobacco, which has no use except for cigarettes and related products, to cease such agriculture and, where feasible, to switch to another cash crop in order to make such products less accessible; and Be it finally RESOLVED, That we encourage the Congress and Senate to terminate all agricultural funding and subsidies to those who plant, grow, or sell any tobacco products." (Sorry for the length, but I thought it would help to show some of the reasoning as well as a number of the resolutions.)
So, anyway, those are some examples of how different religious communities think about tobacco....
