Fish on Fridays
The United States Conference of Catholic Bishops (USCCB) has asked Catholics to pray, fast, and abstain from meat on April 12 “for the justices of the Supreme Court, that they would respect the authentic meaning of marriage by upholding the Defense of Marriage Act.”
The USCCB has asked Catholics to fast and abstain from meat on all Fridays until the conclusion of the Year of Faith.
Defense of Marriage means to uphold the traditional definition that marriage is for procreation. The two people involved should be ordered towards procreation. The operative word here, is "ordered towards." So eighty year old people can have a marriage because their bodies are ordered towards procreation. If they wanted to, they could pump their bodies full of the correct hormones and produce children. I know that's unusual, but it's an example of what is meant by "ordered towards."
