Bishop Richard Malone of Maine issued this letter to all Catholics in Maine. Here is the conclusion:

As we prepare to make these decisions on Election Day, we need to be asking ourselves if our vote will serve to advance human dignity, support life in all of its stages of development, and serve the common good.

A Catholic whose conscience has been properly formed by scripture and Church teaching cannot justify a vote for a candidate or referendum question that opposes the teachings of the Church. The definition of marriage as the union of one man and one woman, open to the birth of children, is a matter of established Catholic doctrine. Any Catholic who supports a redefinition of marriage—or so called “same-sex marriage”—is unfaithful to Catholic doctrine. The group calling itself ‘Catholics for Marriage Equality’ does not speak for the Catholic Church, any more than does ‘Catholics for a Free Choice’, another dissident group that promotes so-called ‘abortion rights’. Faithful Catholics will give no credence to either.

Vote your faith on November 6.”
