Evangelics? because I am catholic that means I am not christian?

I cannot understand your teachings.. salvation by face and some of you say you are saved forever... is that a joke? how it can be true? if the people can be bad and good.. how can they loose their salvation? evangelics write books to promote anti-catholicism.. why is that? it was jesus worry about to promote his church or to convert the people? it wasn't the roman church that gave you the NT totally compiled when Luther wanted to quit the letter of james because all evangelic churches disagree with the salvation by works.. and returning your teachings.. all of you are divided in sects or churches reborns , pentecosts.. ect.. and all of you are the true churches of christ or what? I didn't know Jesus founded many churches instead one church that even the hell won't destroy.. that he said to peter.. or you deny the words of jesus when he said to peter.. you are my rock...
