One way is because The Roman Catholic Church requires members to take part in Holy Communion and believes such worship MUST be led by an authorised Priest. Quakers do not believe that Communion is necessary for spiritual enlightenment and neither is a Priest needed to lead worship.
They are one and the same.

Taoism is a natural philosophy, Catholicism is a revealed religion.
Most forms of Christianity, but the two manin ones that weren't legal in other colonies were Quakerism (not sure that's a word) and Catholicism.
No, there is not a difference between Catholicism in the United States or Great Britain - except for the funny accent; as we are members of One, Holy, catholic, and Apostolic Church. We use the same Missal, Church calendar, and rubrics. And Catholicism is the "original" form of Christianity; as opposed to the myriad of "Flavors" offered today.
The primary difference is the belief and respect for One God(Allah) vs. The trinity. Please see the Related Question below on the differences between Christianity in general and Islam. Most of those differences also apply to Catholicism and Islam.
Anglo-Catholicism and Roman Catholicism are both branches of Christianity, but they have some key differences. One major difference is that Anglo-Catholicism is a subset of Anglicanism, while Roman Catholicism is a separate denomination. Another difference is that Anglo-Catholicism allows for more flexibility in certain beliefs and practices, while Roman Catholicism follows the teachings of the Pope and the Vatican more strictly. Additionally, Roman Catholicism places a greater emphasis on the authority of the Pope and the doctrine of papal infallibility, while Anglo-Catholicism tends to have a more decentralized structure.
One difference between Mormonism and Catholicism is that while Catholicism only has one sacred text, The Bible, Mormonism has a few including; The Bible, The Book of Mormon, The Doctrine and Covenants and The Pear of Great Price. Another difference is that Mormons believe that The Holy Trinity are three distinct beings while Catholics believe that they are one.
The most important difference between Catholicism and Protestantism, although there are many, is the fact that Protestantism does not believe that the Eucharist is the Body, Blood, Soul and Divinity of Jesus Christ, but believes it is only a remembrance.
Catholicism (please note spelling) is just one branch of many within Christianity.
