How can we know something that surpasses or is beyond knowledge? How can we know something that is beyond words?... We can and do use words to point to all of our human experiences. However, the experience of "God as Agape" is beyond words, beyond the limitations of our minds.
If we who self-designate ourselves with terms like "Catholic," "Orthodox," "Protestant," "Evangelical," "Charismatic," "Pentecostal" and others would fully surrender ourselves to The Holy Spirit, we could stop focusing on the secondary words we use to describe the primary experience of The Holy Spirit.
