“My friend says that life begins when the egg and sperm join together. I say that it begins when a baby takes its first breath. Which of us is right?
“The really hot question is, ‘When does being a person begin?’ Most medical authorities and Planned Parenthood agree that it starts when a baby takes its first breath.
“Some of our oldest religions have changed their views about this question many times over the centuries. Today, some people sincerely believe that being a person begins when the egg is fertilized. Some, just as sincerely, believe that it begins with birth. And lots of others believe it begins somewhere in between.
“What we are all sure about is that a pregnant woman is a person. We know for sure that she has morals, feelings, human needs, and a conscience. Because of this, we know that she is the only one able to make a decision about her pregnancy options. She does it based on her own needs, ethics, and religious belief about when being a person begins. It would be wrong to force her to observe someone else’s religious belief.”
