Is A Course in Miracles the only path to the truth?

No. The Course is a comprehensive thought system, which does not require any additions to set us on the way home. Yet the Course makes it abundantly clear that Jesus does not have a monopoly on the truth. Jesus is a manifestation of Christ, as many other world teachers were, and still are. We perceive these teachers as unique and separate human beings, until we have advanced enough to recognise that they are all one and that we are ready to join them in bringing about the salvation of the world.

We live in a world of many cultures, languages and other symbols. Through the centuries, God has not given us only one path back to Him:

"This is a manual for a special curriculum, intended for teachers of a special form of the universal course. There are many thousands of other forms, all with the same outcome." (M-1.4:1-2)

We should, therefore, be careful not to see A Course in Miracles as the only way (or even the best way) to salvation. This is an easy trap to fall into, especially for new students. Other paths may be equally valid, and it is not for us to judge whether someone else is making spiritual progress. Rather than by evangelising, you teach the Course by how you interact with those you meet, and by bringing peace to conflict.

At the same time, we may find it difficult to combine the approach of the Course with that of other religions or philosophies. Many concepts of the Course may conflict with other teachings, and to try to combine another distinct spiritual path with A Course in Miracles, could do a dis-service to both. This comment applies in particular to traditional Christianity and the Course: there are many fundamental differences which make it difficult to follow both paths simultaneously.
