It appears that during this time, Parker was also formulating views on God and man that he would first release in his "Views on the Two Seeds" (1826). Parker taught that all persons are either of the "good seed" of God or of the "bad seed" of Satan (the children of the good seed are roughly equivalent to the "elect" of Calvinism, and those of the bad seed similar to the "non-elect"), and were predestined that way from the beginning. Therefore mission activity was not only unbiblical, but as a practical matter useless, since the "decision" was already made prior to birth.
