The vibrant American Church became fractious: Many priests and religious abandoned their spiritual callings for the world; some theologians dispensed with their obligations to work with the Magisterium;
evangelization suffered; loyalty to Church teaching was rejected in favor of a misguided notion of «conscience;» and dogma and truth were repudiated.
For John Paul II's 1990 encyclical Redemptoris Missio, the Magna Carta of the New
Evangelization, called for urgent evangelism among Christians who had fallen away from the practice of the faith, or had been poorly catechized, or, more likely, had
suffered both maladies, the latter contributing to the former.
