A call to action (CTA) is an explicit prompt to get an immediate response or action from the person reading or hearing it.
Call to Action (CTA) is an American organization that advocates a variety of changes in the Catholic Church. Call To Action's goals are to change church teachings in such areas as mandatory celibacy for priests, the male-only priesthood, the selection process for bishops and popes, and opposition to artificial contraception. The organisation has from its beginning inspired considerable controversy within the Catholic Church in the United States. Cardinal Giovanni Battista Re of the Congregation for Bishops said in 2006 that some of CTA's views are "in contrast" with the Catholic faith. The Diocese of Lincoln, Nebraska has placed the group under the ban of excommunication within the diocese, and several other bishops have censured the organization.
