The Christian must sternly reject any such practice. Paul also condemned legalism in the most stringent terms. No one is to tamper with the word of the sovereign God. The Christian view of freedom of conscience is to be understood in light of the above context. The Christian is free to do anything that is not contrary to the word of God.
Scripture alone is the ultimate standard of ethical activity.
God alone is the Lord of the conscience. Human commandments which are contrary or additional to God's word have no authority over the Christian conscience. Scripture rejects all pagan notions which describe the human body or the physical world in general as evil or inferior to spirit. The Christian ought to rejoice in God's creation to God's glory. As this norm is applied to the question of contraception, then, the Christian is free to use contraception, unless it is forbidden by Scripture.
