There is only ONE opening in-not multiple ones. There were no doors to enter in through the Budha, or through the Mother Earth of New Agers, or through Brahma of Hinduism, or through our ancestors through Shintoism, or through Allah of Islam,etc.
This pluarlism is a poison creeping subtely into Christianity. His opening of the Sanctuary faced east for a reason- He saves us right through His plan laid out in the Sanctuary -For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be. Matthew 24:27 As for the idea of pluralism, He kind of shot that issue down when He said- I am the door: by me if any man enter in, he shall be saved, John 10:9 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. John 14:6
There are Christians organizing what they call "pluralism sunday" for an "inter-faith" day of celebration. But as one can see from above-there are not multiple ways to salvation. As stated on the website PluralismSunday.org---
"On the first Sunday in May- this year, May 6, 2012 (or other times during the year) – churches dedicate their worship to a celebration of our interfaith world. Progressive Christians thank God for religious diversity! .... On PLURALISM SUNDAY, churches celebrate elements of other world faiths in their sermons, litanies, and music; many feature speakers and singers from other faith traditions. Some congregations have exchanges with other faith communities, going to each other’s houses of worship."
