The US Bishops have re-issued a call to American Catholics to pray and fast on Fridays for the protection of all human life, religious liberty and the dignity of marriage and the sacrament of matrimony.
One suggestion is to abstain from eating meat on Fridays (just like the olden days).
Holy Hours, rosaries and specific times for family prayer, e.g. around the shared table are other worthy suggestions.
