What is the difference between the Catholic and Christian religions?
The same as between English and British-English. Catholics are the original variant (together with the Orthodox – those two groups just split in halves about 1.000 years ago), and later other “dialects” of Christianity evolved. If you want to know the difference, you should tell us which other kind of Christians you want to compare them to. Generally, Catholics, like the Orthodox and Oriental churches, accept the Early Church Fathers, the Ecclesiastical Tradition, the seven sacraments, the Authority of the Church (said to be guided by the Holy Spirit) in theological matters, the hierarchy of Bishops, archbishops, and so on, the veneration (but certainly not worship) of saints – just like all the Church did for the first 1.500 years of Christian history. The Protestants generally deny all (or most) of these things, thinking that every Christian should be free to make up their own interpretation of the Christian truths and the message of the Bíble instead of letting God help them through
