Apostolicity Of The Church

Apostolicity is the way that the Church compares itself to the accuracy of its teachings as proclaimed within its early years of establishment by Jesus. This is very important to the Catholic Church, because on of the most important things to the Church is the authenticity of its teachings, and its heritage as seen through succession. All four marks of the Catholic Church are based upon the accuracy of the Church. Consequently, one of the most important things to the Church is maintaing the authenticity of the Magisterium as much as possible.

The Church was given the Holy Spirit to assist in the protection of the Magisterium, as well as the complete guidance of the Church. After Pentecost, the Holy Spirit gave the Apostles the strength to go out and preach the Good News. The term "Apostolic" is very important, as it is the clearest way to describe the relationship between Christ and his Apostels. This represents the sanctity of the authority of the Church, as it all begun with the establishment of God. 

Apostle means, "one who is sent," by the authority of Jesus to continue His Mission upon earth. Therefore the Church is called Apostolic, because it was founded by Jesus. Apostolicity of doctrine and mission is necessary. Apostolicity of requires that the deposit of faith is given to someone with the right committed to the Apostles shall remain unchanged. The Church will withstand the test of time due to the assistance of the Holy Spirit.
