A new study finds that among people who attend church, only 30% are completely loyal to the denomination they are currently attending (meaning they would only consider attending church within that specific denomination). Another 44% prefer their current denomination, but would be willing to consider others. Denominational loyalty differs dramatically between Catholics and Protestants. Six out of ten Catholics will only consider attending a Roman Catholic church, while Protestants are about as likely to be loyal to their toothpaste or bathroom tissue as they are to their current denomination.
