Here is a part of the Adventist
official statement on birth control:
5. Appropriate methods of birth control. Moral decision making about the choice and use of the various birth control agents must stem from an understanding of their probable effects on physical and emotional health, the manner in which the various agents operate, and the financial expenditure involved. A variety of methods of birth control--including barrier methods, spermicides, and sterilization--prevent conception and are morally acceptable. Some other birth-control methods may prevent the release of the egg (ovulation), may prevent the union of egg and sperm (fertilization), or may prevent attachment of the already fertilized egg (implantation). Because of uncertainty about how they will function in any given instance, they may be morally suspect for people who believe that protectable human life begins at fertilization. However, since the majority of fertilized ova naturally fail to implant or are lost after implantation, even when birth control methods are not being used, hormonal methods of birth control and IUDs, which represent a similar process, may be viewed as morally acceptable. Abortion, the intentional termination of an established pregnancy, is not morally acceptable for purposes of birth control.
6. Misuse of birth control. Though the increased ability to manage fertility and protect against sexually transmitted disease may be useful to many married couples, birth control can be misused. For example, those who would engage in premarital and extramarital sexual relations may more readily indulge in such behaviors because of the availability of birth control methods. The use of such methods to protect sex outside of marriage may reduce the risks of sexually transmitted diseases and/or pregnancy. Sex outside of marriage, however, is both harmful and immoral, whether or not these risks have been diminished.
7. A redemptive approach. The availability of birth-control methods makes education about sexuality and morality even more imperative. Less effort should be put forth in condemnation and more in education and redemptive approaches that seek to allow each individual to be persuaded by the deep movings of the Holy Spirit.
I know some Adventists who strongly oppose any contraceptive measures that are not "natural." Most of them are people who also oppose the use of medicinal drugs and most medical treatment in general, so they object to hormonal options or sterilization, for example. They will use herbal remedies (which have been highly ineffective for them) and natural family planning techniques. They are usually at the extremely conservative end of the Adventist spectrum in their views on a lot of other issues as well. However, the Adventist Church in general doesn't take an anti-contraception position. They leave it up to the individual to decide.
Also, here is a portion of the
official statement on abortion. Notice that it specifies that Adventist institutions should develop their own policies in harmony with these guidelines and that they shouldn't require any medical personnel to perform such procedures if they have religious or ethical objections to abortion.
4) The Church does not serve as conscience for individuals; however, it should provide moral guidance. Abortions for reasons of birth control, gender selection, or convenience are not condoned by the Church. Women, at times however, may face exceptional circumstances that present serious moral or medical dilemmas, such as significant threats to the pregnant woman's life, serious jeopardy to her health, severe congenital defects carefully diagnosed in the fetus, and pregnancy resulting from rape or incest. The final decision whether to terminate the pregnancy or not should be made by the pregnant woman after appropriate consultation. She should be aided in her decision by accurate information, biblical principles, and the guidance of the Holy Spirit. Moreover, these decisions are best made within the context of healthy family relationships.
5) Christians acknowledge as first and foremost their accountability to God. They seek balance between the exercise of individual liberty and their accountability to the faith community and the larger society and its laws. They make their choices according to scripture and the laws of God rather than the norms of society. Therefore, any attempts to coerce women either to remain pregnant or to terminate pregnancy should be rejected as infringements of personal freedom.
6) Church institutions should be provided with guidelines for developing their own institutional policies in harmony with this statement. Persons having a religious or ethical objection to abortion should not be required to participate in the performance of abortions.
7) Church members should be encouraged to participate in the ongoing consideration of their moral responsibilities with regard to abortion in light of the teaching of scripture.
I don't have any personal experience with Adventist hospitals, but if they are performing abortions on demand and not for the reasons listed above, then they are not in accordance with the official guidelines.
