Birth Control

Updated: Apr 17



For Christians, the topic of birth control is closely tied to beliefs about the sanctity of human life, God’s design for marriage, and human responsibility in stewarding fertility. In a culture that treats contraception as morally neutral or unrelated to one’s personal faith, a biblical worldview calls us to thoughtful discernment grounded in truth.



Asking the Right Questions

Not all methods of birth control are the same, and understanding how each method works is essential to evaluating them ethically. Dr. Chris Cirucci, a board-certified OB-GYN with more than 20 years of clinical experience and chair of the board of directors at the American Association of Pro-Life Obstetricians and Gynecologists, says Christians should start with two critical questions:


  1. Is it morally acceptable to use artificial means to prevent conception at all?

    Within the broader Christian community, there is disagreement on this point. The Roman Catholic Church teaches that all artificial contraception is morally wrong because it intentionally prevents the procreative potential of sex, which is understood as an essential aspect of the marital act. Some Protestants also hold this view, and we respect the conviction and theology behind it. Most Protestants, however, are open to contraception that does not violate the sanctity of human life, leading to a second important question.


  2. How does birth control work?

    The answer will differ based on the form of contraception. Before addressing these, let’s define the process of conception. Fertilization occurs when a sperm meets an egg in the fallopian tube, forming a zygote—a new human being with a unique genetic identity. This embryo then travels to the uterus over the next several days before implanting into the uterine lining approximately one week after conception.A biblical worldview affirms that life begins at conception, the moment the egg and sperm join to form the embryo. Christians must evaluate birth control methods based on where they act in the timeline of conception. Do they prevent fertilization? Or do they interfere with a human life that has already begun?



Methods that Prevent Fertilization

Forms of contraception like condoms, diaphragms, cervical caps, and sponges physically block sperm from reaching the egg. These barrier methods are consistent with a pro-life ethic because they prevent sperm and egg from meeting, acting before fertilization occurs. 


Similarly, sterilization procedures such as tubal ligation or vasectomy prevent sperm and egg from coming into contact. Behavioral methods, such as withdrawal or fertility awareness-based methods—often called natural family planning (NFP)—also fall into this category. Because they do not interfere with an existing human life, they do not raise the same ethical concerns as other methods.



Hormonal Contraceptives

Hormonal birth control comes with more complexity. The combination pill, which contains both estrogen and progesterone, is one of the most commonly used forms. It works primarily by preventing ovulation, meaning no egg is released for fertilization. Theoretically, its secondary mechanism—thickening cervical mucus or thinning the uterine lining—could prevent implantation of a fertilized embryo, but research on whether this actually happens is unclear. Because it stops conception before it occurs, Dr. Cirucci is comfortable prescribing the combination pill and considers it generally acceptable from a pro-life standpoint, while recognizing that some pro-life Christians may still object.


Other delivery methods that use the same hormones, such as the patch or vaginal ring, fall into this same ethical category. Depo-Provera, an injection of progesterone given every three months, is also successful at preventing ovulation and vastly reducing the risk of fertilization, making it an ethical choice for pro-life Christians in Dr. Cirucci’s view.



Methods That Raise Ethical Concerns

Some forms of contraception do not consistently prevent ovulation. Instead, they are designed to act after fertilization has occurred to prevent uterine implantation. This is where we, at CFBU, draw an ethical line. 


One example is the progesterone-only birth control pill, often called the “mini-pill,” which alters the uterine lining in ways that may prevent a fertilized embryo from implanting. The result is the loss of a newly formed human life. We consider these methods to be abortifacients and, therefore, unethical for biblical Christians.


Intrauterine devices (IUDs), both hormonal and copper, function in a similar way and raise similar concerns. They may sometimes inhibit ovulation, but they also create an environment in the uterus that can prevent implantation. For this reason, Dr. Cirucci does not recommend IUDs.



Emergency Contraception

Commonly known as the morning-after pill, emergency contraception adds another layer of complexity to the contraception conversation. Drugs used in emergency contraception include levonorgestrel and/or ulipristal acetate (Ella), which can work in different ways depending on timing. While in some cases they may delay ovulation, they can also prevent implantation. Because of this uncertainty, we find these drugs problematic. If there is a real possibility that a drug acts after fertilization, Dr. Cirucci believes it risks ending a human life.



Redefining Pregnancy

A recent shift in medical terminology muddies the waters around conception and implantation. In much of modern medical literature, pregnancy is defined as beginning at implantation rather than conception. Under this definition, anything occurring before implantation is not classified as an abortion. As a result, some physicians may claim a method is not abortifacient, even if it prevents a fertilized embryo from implanting.


For Christian couples, this highlights the importance of asking specific questions. Instead of “Does this cause abortion?” Dr. Cirucci advises patients to ask, “How does this method work?” Understanding the mechanism helps Christians make informed, biblically grounded decisions about which method they choose.



Thoughtful Discernment

Ultimately, the question of birth control is not one-size-fits-all within the Christian community. Faithful believers arrive at different conclusions on the question of whether contraception itself is permissible.


However, Dr. Cirucci’s framework presents a consistent principle: If human life begins at conception, any method that risks ending that life is unethical. At CFBU, we affirm this stance and encourage believers to engage with both Scripture and science to understand the mechanics of contraception methods and make choices consistent with a pro-life ethic.
