After 500 Years, Reformation-Era Divisions Have Lost Much of Their Potency – Pew Study on Religion 

As Protestants prepare to mark the 500th anniversary of the Reformation, two new surveys show the theological differences that split Western Christianity in the 1500s have diminished.

Just because most people do not see the theological difference, does not mean that the difference is not there. In 2016 the Pope extended the power to forgive to all Roman priests, the implicit point here is that the Pope can forgive other peoples sins. This is different from the Protestant theology which emphasizes justification through faith that no man can boast.

This study highlights a symptom of a wider issue that is going on in Christianity right now, and that is Christians are not reading their bibles.  Superficially Catholics and Protestants are the same in that they pray to the same God but fundamentally these two faiths are different in the way they interpret the Bible. This can be seen in the way church leadership is set. Protestant reject the idea of the Pope being the head of the church on earth.

Another example is Holy communion, in Catholic theology communion represents the actual body of Jesus Christ and his Christ, while in Protestant theology holly communion is a representation and is only performed as a ritual in remembrance of the death and resurrection.

Secondly, Celibacy, Catholics demand people abstain from sexual activity and not marry if they are to serve as priests. On the other hand, Protestants are allowed to marry and they are no obligations for them to remain celibate. 500 years after the Reformation there is still a very big difference between the two faiths, it is good they are not fighting and killing each other.

Another difference is the importance Catholics put on sainthood, in Protestant theology these saints like every one of us that also need God.
