Taking the Pathfinder courses with the Philos Project, I would certainly say I really deepened my understanding of Christianity. I had a fairly good understanding of Christianity prior to starting the Pathfinder Certification Course. But, I understand Christianity and the various Christian sects around the world with Philos Project.
Education is certainly important in being able to personally improve relationships with Christians from other traditions. I attend Church services of another denomination. That’s another tangible way to improve relationships with other Christians as well. Another tangible way I would give for personally improving relationships with other Christians of other tradition is through interfaith dialogue and interfaith service. These things and other things we could do build bridges between the various Christian traditions.
