The original answer about Mary’s sinlessness
Claim examined: Christian conduct and moral questions
Scriptural Answer
Catholics also CLAIM that Mary was "without sin" however this FALSE DOCTRINE is also NOT taught in the word of God. God said in Romams 3:23 "for all have sinned and fall short of the glory of God," and this INCLUDES Mary. God said in 1 John 1:8, "If we say that we have no sin, we deceive ourselves, and the truth is not in us." Catholics say that Mary was without sin, so the TRUTH is NOT in them!! The ONLY human to ever walk this earth WITHOUT SIN was our Lord and Saviour Jesus Christ for God said in 1 Peter 2:22, "Who committed no sin, Nor was deceit found in His mouth"
