One of the most frustrating aspects of my own personal witness for Christ is the heresies taught by so many different cults and sects. Things like "pray to Mary because she can get things from God that Jesus cannot," "partake of the sacraments and you will receive a portion of God's grace," or "water baptism leads to (eventual) salvation." Frustrating does not even begin to describe my mental state when I hear these or any number of other heresies taught as official dogma.
All we can really do is rely on God and His Truth, and defend the faith with His Truth above all else.
