In this position, all religions including Christianity are relative. Only God is Absolute. Religions in general are complete systems in themselves and capable of helping their adherents find salvation or ultimate enlightenment. Each religious tradition or vehicle has its own means or routes for reaching their destination. This destination is variously called God, Allah, the Toa, Great Spirit, Brahman, Nirvana, Sunyata, Tien , Holy One etc.
Truth is only one but the sages call it by different names.
Moreover the models and makes of each vehicle differ as do their function. In other words, the individual differences across various religions are as different as the types and makes of vehicles on the highway. Some vehicles may be better able to perform certain functions but are not so good in other areas. For instance, one vehicle may be better at negotiating winding roads, but not so good at climbing steep hills or slippery ground. Another vehicle may have more comfortable seats but may not be mechanically as efficient as others that are less comfortable.
