The religion is Judaism. A person who follows Judaism is Jewish.
that person would be called a religiously tolerant person.
That depends on the religion of the person as well as their language.
It rather depends on your relation to the person, his religion, and his motives.If you are of the same religion and agree with his motives he might be a saint or martyr.If the person is an opposing religion he might be deluded, a fanatic or insaneif you are an atheist he would be deluded, mis lead, mistaken or potentially insane
A person who believes in a higher power but does not adhere to a specific religion may be called a spiritual person, a deist, or someone who is spiritual but not religious. These individuals may believe in a higher power or universal force without following the doctrines of organized religion.
Its depends on that person's religion. If they are Christian then you call them Christians, if they are Mormon then you call them Mormon's. Whatever their religion is that is was you call them. Hope this helps you.
The answer is Convert. My friend answer is totally wrong that he says yes you can convert to any religion and you are free in this case. Yes you are free to change religion and but in case of Islam, once you entered in this religion then you have no option to leave it. Additionally, the religion of the person prior to conversion will typically see that person as an apostate or heretic.
A Believer =) a cristian or a jew. And Muslims.
