A. Every single Biblical Text that specifically addresses the moral state of infants at birth unanimously demand infants are sinners/unclean at birth:
Job 25:4 How then can man be justified with God? or how can he be clean that is born of a woman?
Job 15:14 What is man, that he should be clean? and he which is born of a woman, that he should be righteous?
15 Behold, he putteth no trust in his saints; yea, the heavens are not clean in his sight.
16 How much more abominable and filthy is man, which drinketh iniquity like water?
Job 14:1 1 ¶ Man that is born of a woman is of few days, and full of trouble......4 Who can bring a clean thing out of an unclean? not one. 5 Seeing his days are determined, the number of his months are with thee, thou hast appointed his bounds that he cannot pass;
Job 5:7 Yet man is born unto trouble, as the sparks fly upward.
Ps 51:5 Behold, I was shapen in iniquity; and in sin did my mother conceive me.
Psa. 58:3 The wicked are estranged from the womb: they go astray as soon as they be born, speaking lies.
Pr 22:15 ¶ Foolishness is bound in the heart of a child; but the rod of correction shall drive it far from him.
Joh 3:6 That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
Gen. 8:21 And the LORD smelled a sweet savour; and the LORD said in his heart, I will not again curse the ground any more for man’s sake; for the imagination of man’s heart is evil from his youth; neither will I again smite any more every thing living, as I have done.
Isa 48:8 Yea, thou heardest not; yea, thou knewest not; yea, from that time that thine ear was not opened: for I knew that thou wouldest deal very treacherously, and wast called a transgressor from the womb.
B. Symbolically bearing children make the mother unclean:
Le 12:2 Speak unto the children of Israel, saying, If a woman have conceived seed, and born a man child: then she shall be unclean seven days; according to the days of the separation for her infirmity shall she be unclean.
C. Observational Evidence
Infants need no training, no examples, no rational choice to display attitudes and actions that cannot be attributed to the fruits of the Spirit but characterize the fruits of the flesh.
D. Definition of Sin
1. Jesus defines sin to be wrong "thoughts" or a sinful condition of heart:
Mt. 15:19 For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies:
Mt. 5:28 But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
2. Paul defines sin as coming short of the glory of God:
Rom. 3:23 For all have sinned, and come short of the glory of God;
1Co 10:31 Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God.
Col 3:17 And whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by him.
Col 3:23 And whatsoever ye do, do it heartily, as to the Lord, and not unto men;
Responses by those who believe children are born sinless:
1. They must EXPLAIN AWAY the above texts.
2. They have no biblical texts that address the moral character of infants (except Messanic prophecies that refer to a virgin born child)
3. They must INFER their position from texts that can be easily interpreted to harmonize with the above texts (e.g. Heb. 2:17).
4. They must limit the definition of sin to willful acts
