"The public has the right to expect guidance from the Church on the moral aspects of birth control. As to the necessity for some form of effective control of the size of the family and spacing of children, and consequently of control of conception, there can be no question. It is recognized by all churches and physicians. There is general agreement that sex union between husbands and wives as an expression of mutual affection without relation to procreation is right. This is recognized by the Scriptures, by all branches of the Christian Church, by social and medical science, and by the good sense and idealism of mankind."
