  Lutheranism identifies with the theology of Martin Luther, a German monk and priest, ecclesiastical reformer, and theologian.
  
  Lutheranism advocates a doctrine of justification "by grace alone through faith alone on the basis of Scripture alone ", the doctrine that scripture is the final authority on all matters of faith, rejecting the assertion made by Catholic leaders at the Council of Trent that authority comes from both Scriptures and Tradition. In addition, Lutherans accept the teachings of the first four ecumenical councils of the undivided Christian Church.
  
  Unlike the Reformed tradition, Lutherans retain many of the liturgical practices and sacramental teachings of the pre-Reformation Church with an emphasis on the Eucharist, or Lord's Supper. Lutheran theology differs from Reformed theology in Christology, the purpose of God's Law, divine grace, the concept of perseverance of the saints, and predestination.
  
  Today, Lutheranism is one of the largest branches of Protestantism. With approximately 80 million adherents, it constitutes the third most common Protestant confession after historically Pentecostal denominations and Anglicanism. The Lutheran World Federation, the largest global communion of Lutheran churches represents over 72 million people. Both of these figures miscount Lutherans worldwide as many members of more generically Protestant LWF member church bodies do not self-identify as Lutheran or attend congregations that self-identify as Lutheran. Additionally, there are other international organizations such as the Global Confessional and Missional Lutheran Forum, International Lutheran Council and the Confessional Evangelical Lutheran Conference, as well as Lutheran denominations that are not necessarily a member of an international organization.
