I hear people speak of being ‘spiritual but not religious’ or about being against organized religion. These are just two ways of saying, “I want to define spiritual activity by my own rules,” which is exactly what Adam and Eve did in their attempt to interpret reality by their own knowledge and wisdom.
To rightly understand the Christian faith, one needs to go back to the beginning and build from there. The incarnation took place and when Jesus was thirty years old, he began his ministry. He did so by choosing twelve disciples, whom he instructed in right thinking, right words, and right actions. He did not tell them to look within themselves and figure it out.
After his death, resurrection, and ascension, these disciples became apostles and by the filling and guidance of the Holy Spirit, they began traveling around the known world, preaching the gospel, and establishing churches based on the teaching they learned from Jesus. They did speak ambiguously, telling people to look within themselves and form their beliefs based on their experiences. What Jesus taught the apostles; the apostles taught the first-generation church.
These churches were established in unity, all believing the same doctrines and practicing the same faith. Within a few generations, other people came along and began to introduce contrary doctrines and practices, which required the churches to gather as a unity and say, “here are the doctrines that the church has always believed and taught.” Anything outside of or contrary to that apostolic teaching was rejected and identified as heresy.
The foundation of the Christian church is that which Jesus taught the apostles, and what the apostles taught to the first-generation church. It was specific, articulate, identifiable doctrine and those beliefs and practices have been handed down to this day, protected and guided by the Holy Spirit within the Church.
