Well, I had only read the headlines of those articles but just now saw a thoughtful well documented article that actually listed the question asked.
Of the following two statements which one better fits your beliefs?
A “My religion is the one, true faith leading to eternal life” or B “many religions can lead to eternal life.”
The article at Scripps News gives a pretty good summary of why this question cannot be used to judge whether Evangelical or other Christian, Muslim and Jewish believers have abandoned basic principles of their faith. Basically the summary comes down to the definition of “Religion”.
If you define Religion as “a set of beliefs a person practices in line with sacred texts and tradition” or if you define Religions as referring to the overall largest Religions including “Christianity, Muslim, Jewish, Buddhist, Taoist, Wiccan, Morman and Atheist” or if you defined the work Religion in the context of the question as only referring to your Religions denominations or sects so “Baptist, Catholic, Roman Catholic, Lutheran, Prebysterian, United Methodist, Non Denominational Christian, Episcopal and such”
The definition of Religion therefore interprets the question and colors the responses both the person who believes there are many ways to heave such as Taoist, and Buddhist and the Christian who believes that there are multiple Denominations that also hold true to the core of Christianity would say B especially if they didn’t consider Muslim, Jewish Wiccan and Taoist as inside their realm of knowledge or experience.
So bottom line is the survey skews the responses by asking an inprecise question and formulating a broad corrleation of Evangelicals abandoning the truths of John 14:5-7
Thomas said to him, “Lord, we don’t know where you are going, so how can we >> know the way?” 6Jesus answered, “I am the way and the truth and the life. >> No one comes to the Father except through me. 7If you really knew me, you >> would know[a >> ] >> > my Father as well. From now on, you do know him and have seen him.” >
So now you know. . .
