'Catholic' (KATH-uh-lik)
‘Catholic’ can mean three different things. Pay attention to the context, so you don’t mix them up!
‘Catholic’ (with a capital ‘C’) can be an adjective. For example
Thomas Aquinas was a Catholic theologian.
Notre Dame is a Catholic cathedral.
It means ‘related to the Catholic Church’.
The Catholic Church is one of the oldest Christian denominations.
At around 1.4 billion members, it is also the largest denomination in the world today.
It is led by the Bishop of Rome, ‘the Pope’ (currently Leo XIV).
For the exam, it is important to know the Catholic Church’s teaching on:
Original Sin
The Sacraments
Baptism
Holy Communion
Just War Doctrine
‘Catholic’ can also be a noun. For example:
Mary I was a Catholic.
Elizabeth I was a Protestant.
In this case, it means ‘someone who belongs to the Catholic Church’.
‘catholic’ (with a lower-case ‘c’) is also an adjective.
It means ‘universal’ or ‘all-encompassing’.
The ‘Catholic Church’ call themselves ‘Catholic’ because they claim to be the universal church.
However, you will sometimes hear Protestants talk about the ‘catholic Church’.
By this they mean everyone in the world who sincerely follows Jesus, regardless of what denomination they actually belong to.
