A long time ago, I learned from the Catholic priests and nuns. Then I learned from the Oneness Jesus only Pentecostals. Then I learned from an unnamed group who often call themselves the body of Christ. From each of these as I was drawn by God something not good was left behind as "I came out of her".
The real connection to the final one of those mentioned was severed more than 10 years ago. The last remaining strand of that connection was cut somewhat later than that, but now I do not walk unconnected to anyone. My connection is to the Head, which is Jesus, as it should be by means of the Holy Spirit. I always knew this needed to be without understanding it. Still the understanding is as through a glass darkly but it is clearer than ever it was before. There is no man I have known that could lead me along this pathway toward the "then" of I Cor 13:12. Yet, when I do quench the Spirit within me that would lead, I am led closer to that "face to face" vision which Moses desired and for which David sought.
Give God the glory!
