What is the most convincing argument for Catholicism's credibility?

I am a 17 year old protestant from britain. I am in mental anguish over whether to become a Catholic or not. I’ve been doing lots of research to find out the truth but I have just become tired and confused. If Catholicism is true what is the most convincing way for me to know it is?
Please help, Thanks.

Dear Mo,

In a word, history. This is what convinced your fellow country-man, John Henry Newman. He said that to know history is to be Catholic. This web sight has his writings. Just keep clicking until you see text:


You are in my prayers. Happy Easter!

Fr. Vincent Serpa, O.P.
