For me personally, the most unbelieveable aspect of it is that we will all be happier when we die, and then will live forever. The most valuable precept of this religion is Christ's advocating Charity (love of other humans) and Forgiveness. All religions have moral precepts of "right" and "wrong" that are translated into laws, rules and regulations in secular societies, and are the laws in theistic societies. What I think organized religion has contributed to human beings living with one another are these rules and regulations that attempt to create a fairness within a society, but not all religious tenets and beliefs are benign. Most are intolerant of what the other belief system posits and will fight "Holy Wars" in the name of their system. We've seen and continue to see this with the current wars in Iran and Afganistan, but it is not something of recent origin. History is replete with accounts of religion, or belief systems causing human misery, wars, deaths, torture, and all those good things. My opinion of Christianity in the US is that is has become more influential in our civic life. Unless a politician states a belief in a personal "God", he or she cannot be elected in the present climate -- non believers need not apply.
I think the inquirer was asking about which 5 languages are referred to as Romance Languages, which then were sometimes called Languages of love because of the descriptive word "Romance". The 5 broard categories of these are Italian, Spanish, French, Portugese, and Romanian because approximately 90% of these languages are rooted, or derived from Latin, the language used by the Romans, hence "Romance" ascribed to them. The interesting question is when the word "romance" became associated with feelings of love and affection.
