Family traits can be the convenient justification for the worst behavior and have the effect of enslaving the individual to a lie. The nature of family relationships tends to repeat the lie over and over until it is accepted as Gospel! Where is God in this? Nowhere! In fact it is a denial of God’s government of man, a denial of man’s inherent individuality as an idea of God.
It is so tempting to assign the family trait curse when a similar characteristic appears - stubbornness, over-sensitivity, absent-mindedness, etc., but beware of the cost of yielding to such a temptation. "Heredity is a prolific subject for mortal belief to pin theories upon; but if we learn that nothing is real but the right, we shall have no dangerous inheritances, and fleshly ills will disappear.” (S&H)
Instead of laying a curse on a family member, whether present or absent, would not this thought be a better?
"The great truth in the Science of being, that the real man was, is, and ever shall be perfect, is incontrovertible; for if man is the image, reflection, of God, he is neither inverted nor subverted, but upright and Godlike." (S&H)
