Does "The Pill" cause abortions?

Even if you believe that non-abortive birth control is an acceptable option for a Christian, there is a big debate about whether the birth control pill -- the oral contraceptive -- is truly a contraceptive or if it can sometimes act as an abortifacient. Imago Dei has a very helpful post outlining the scientific issues involved and drawing some conclusions. The pill acts to prevent the ovary from releasing an egg and also can thicken cervical mucus to create a barrier to sperm; in those two ways of acting, it prevents conception from occurring.

The question is, if fertilization occurs anyway, and a new life comes into being, does the Pill create a hostile environment for the embryo, preventing it from implanting. In such a scenario, the Pill would cause the death of an unborn child. In other words, it would act as an abortifacient. The problem is that we don't have direct evidence establishing that that can happen or definitively ruling it out. There are theoretical arguments made for both sides, and some Christians would argue that any possibility that this could occur is reason enough not to use the Pill.

I encourage you to read and respond to the post on Imago Dei.
