The Protestant including the Mormon churches have never really protested, separated and reformed from the very basic doctrines of the Roman Catholic church.  

1- They still follow the very Roman Catholic Paul. a 325 A.D. creation of the RC Church.  Paul was given a predominant position in the New Testament.  The Protestant churches have followed and use the Pauline gospel without hesitation or reservation.

2- They use the Roman Catholic Gregorian calendar.  This calendar was given the church's imprimatur by Pope Gregory in 1582 with the British Empire changing from the Julian Calendar to the Gregorian in 1752. The Greek Orthodox church still uses the Julian calendar which is 13 days behind the current Gregorian calendar.   The Israelites never used a calendar which had its beginning about 10 days after the winter solstice.  The Gregorian calendar has no reference to the calendar or holy days described in the Old Testament. The Julian and Gregorian calendars have no reference to the Vernal Equinox which is the basis of the Israelite calendar.  The use of Sunday as a day of worship is in violation of the true Israelite calendar which proscribes the three mandated feasts, Passover, Pentecost, Tabernacles, Sign Day and Sabbath days ultimately based upon the Vernal Equinox.

3- They observe Easter and Christmas as so-called Christian holidays.  Nothing could be farther from the truth. Neither Christ nor any of the Apostles ever celebrated Easter or Christmas.

4- They use and follow the Apostle's Creed.  This creed has the abominations that Christ descended into hell and that the Holy Ghost is the father of Christ.  It represents a fundamental lack of understanding of the three days that Christ visited the word of spirits.  The concept that Christ, a perfectly resurrected God, who went down into hell is blasphemy beyond belief.

5- They most generally use the symbol of  the "Cross".  This is an abomination as it has reference to Christ's suffering and utter lack of respect.  Neither Christ nor any apostle ever used the "Cross" as a symbol.

6- They use responsive readings.  This is thought control if there ever were such a thing.  The leader speaks typically following some printed text  and the followers respond without any examination or thought of what they are saying.

7-  Generally, with the exception of Baptists,  they use infant baptism as a sacrament.

8-  They both use the incorrect term of "Jesus" for Yahshua.    The letter "J" was never in the English language till the 14th century.  Note that the Geneva Bible of 1560 has no "J" in it, what-so-ever.

9 - Last and possibly most importantly, Protestants as well as Mormons use bibles which are all essentially Roman Catholic that had the cannon fixed in 325 A.D. with the exception of the Apocrypha being removed. All of these bibles have the writings of Roman Catholic Paul.  Read the following and see how many characteristics of the so called Protestant churches were not just copied from the Roman Catholic church but instituted as their foundation.

Most of what follows is from other authors from the Internet.  I have only made minor revisions. -- 

Council of Nicaea, First Ecumenical Council - 325 A.D. (Christian Era)

The year was 325 A.D. according to the Roman calendar. A council was convened by order of Constantine, the Roman emperor. He had been a leader in the cult known as Sol Invictus (Invincible Sun) and now wanted to unite the Christian sects in the empire under his existing church; the Universal Church of Rome. Many changes to the religion of Christianity were about to take place at that council, including: 

 Formulation for wording concerning the Trinity based on Anthanias (description of the formulation  is mentioned below) 
 Changing Verses of Bible 
 Eliminating certain verses and books from the Bible 
 Declaring Arian's "unitarian" (belief in the Unity of God) as heresy 
 Changing the day of worship from Saturday to Sunday 
 Changing the date of Jesus' birthday to December 25th 
 Introduction of Easter (pagan worship called "Feast of Ishtar") 
 Church of Roman "officially" became the "Universal Church of the Holy Roman Empire" (the word 'Catholic' means 'universal' 
The Roman Catholic Church took on a new face. 

What follows is a quote from the Roman Catholic Church. It is their explanation behind the many changes occurring during the Nicaea Council. 

Nicaea or Nicea (/naɪˈsiːə/; Greek: Νίκαια, Turkish: İznik) was an ancient city in northwestern Anatolia, Turkey, and is primarily known as the site of the First and Second Councils of Nicaea (the first and seventh Ecumenical councils in the early history of the Christian Church), the Nicene Creed (which comes from the First Council), and as the capital city of the Empire of Nicaea following the Fourth Crusade in 1204, until the recapture of Constantinople by the Byzantines in 1261.

In tracing the origin of the Bible, one is led to AD 325, when Constantine the Great called the First Council of Nicaea, composed of 300 religious leaders. Three centuries after Jesus lived, this council was given the task of separating divinely inspired writings from those of questionable origin. The actual compilation of the Bible was an incredibly complicated project that involved churchmen of many varying beliefs, in an  atmosphere of dissension, jealousy, intolerance, persecution and bigotry.  At this time, the question of the divinity of Jesus had split the church into two factions.  Constantine offered to make the little-known  Christian sect the official state religion if the Christians would settle their differences. Apparently, he didn't particularly care what  they believed in as long as they agreed upon a belief.  By compiling a book of sacred writings, Constantine thought that the book would give  authority to the new church which ultimately became the Roman Catholic Church.


Basically the canon decided at the Council of Nicea has been the root of all subsequent bibles.  The main difference was the removal of the 14 books of the Apocrypha from the King James Bible.  The Apocrypha is a selection of books which were included in the original 1611 King James Bible. These apocryphal books were positioned between the Old and New Testament (it also contained maps and genealogies). The Apocrypha was a part of the KJV for 274 years until being removed in 1885 A.D. A portion of these books were called deuterocanonical books by some entities, such as the Catholic church.
