Confessional Range of Protestantism

Diversity and the fragmented nature of Protestantism are the reason of various interpretations of its boundaries and the number of denominations it comprises. The key criterion of affiliation with Protestantism is the acceptance of basic doctrines set forward in the Niceno- Constantinopolitan Creed. The analysis of the beliefs of the religious organizations traditionally connected with Protestantism suggests that Jehovah's Witnesses, the Church of Jesus Christ of Latter-day Saints, Pentecostals-Unitarians are out of the doctrinal field of Christianity in general and out of the range of Protestantism in particular. The other distinct characteristic of Protestantism is the acceptance of the Five Solas – sola scriptura, sola fide, sola gratia, Solus Christus и Soli Deo gloria, which are aimed at the validation of Christian doctrines set forth in the Bible. This thesis was demonstrated via the analysis of the doctrinal sources of Lutheranism, Reformed Church and Anglican Church. The article also reports on the five solas present in the creeds of Baptists, Pentecostals, Methodists, Mennonites, Religious Society of Friends, and Seventh-Day Adventists. Cultural and historical proximity of protestants and religious organizations that do not meet the criteria above calls for a new category – “post reformation religions” – that can embrace them all.
