It differs from exclusivism because they do not completely disregard other beliefs. But, nor do they completely accept it. They are just tolerant about it. The ultimate faith of inclusivism leads to Christ and Christian values. This means that according to a follower of inclusivism, there is not salvation in non-Christian beliefs because they do not have Christ with them. An inclusivist would say that the God is merciful and kind and salvation can be achieved through Jesus Christ. He could say though that as long as a person follows Christian morals (even if they are not Christians) they will be saved by Christ. So they are tolerant towards others but Christ is still a necessary requirement for reaching heaven. Inclusivism's strength is that it incorporates other religions and has a certain amount of openness. It does not condemn other religions too. But, the weakness is that it takes only half a step towards inviting other religions but does not make a full effort to understand them. Tolerance is prevalent, not understanding. .
The third bracket mentioned was that of Pluralism. Pluralism defines God as divine and mysterious. It says that Christ is not the only God; Christ is the way Christians seek God. Therefore, other religions are welcome to follow their own Gods. There is no exclusion and it has a very open attitude towards other religions. Pluralists also read the Bible with an open mind and do not always take it literally, rather they understand it with prior context in mind. A way to understand pluralism better is imagining a mountain with the peak being God. Pluralism teaches that like there is more than one way to reach the mountain top and different people might take different trails and paths. Likewise, there are multiple ways to reach God. Different religions are just different paths to reach God. They understand that their personal way of reaching the peak of the mountain is with the help of the Christian path but others do not have to necessarily take the same path.
