Dear Igbinoba,

Thanks for the question.
This is a common question; it's even in our searchable knowledge base.
There are a lot of quick answers there, so give it a try.

I searched the knowledge base for you and found these web postings that should answer most, if not, all of your question:

• In what fundamental ways does the Catholic Church differ from the Protestant denominations?
• What are the major differences between Catholics and Pentecostals?
• What are the major differences between Baptists and Catholics and how do I become a Catholic?
• What differences remain between the Orthodox Church and ours and what's the Pope's view?
• What is the fundamental difference between the Catholic Church and the Church of England?
• How were the differences resolved between the Armenian Apostolic and Catholic Church?
• What are the differences between the Catholic and (AME) African Methodist Episcopal Churches?
• How does the Catholic understanding of grace differ from the Calvinist?
• Do the differences among Catholics and Protestants come down to perceptions of life after death?
• A Protestant Christian tries to correct the errors heard on the Catholic teaching on justification. (Video)
• Could you explain the Protestant view of the Rapture and how it squares with the Catholic view?
  

If you are interested in the history of each faith check out:

• When was your church founded?

and my favorites page for good reasons to become a Catholic along with some video testimonies.

I hope this helps,

Mike
