An excerpt from their letter published today:
Upholding the present definition of marriage does not depend on anyone’s religious beliefs. Washington State’s present law defining marriage as “a civil contract between a male and a female” is grounded not in faith, but in reason and the experience of society. It recognizes the value of marriage as a bond of personal relationships, but also in terms of the unique and irreplaceable potential of a man and woman to conceive and nurture new life, thus contributing to the continuation of the human race. A change in legislation would mean that the state would no longer recognize the unique sacrifices and contributions made by these couples, thereby adding to the forces already undermining family life today.
For these reasons, we the Catholic Bishops of Washington State call on the citizens of this state to maintain the legal definition of marriage. We ask all to join in praying with us for married couples and families and to do everything possible to support them.
