How Newton's first law is related to chastity
After defining chastity and Newton's first law we can now use Newton's first law to explain chastity as well. An "object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force". Let's just say that a person will remain pure (at rest or at uniform motion in straight line) unless compelled to change his state of sexual purity by having sex ( by the action of an external force). Newton's first law attest the thought of religious who state that a virgin or a person abstained from sexual intercourse is clean in his thoughts, words, and actions as an object remain in state of rest or uniform motion. A vow of chastity is a constant devotion to God for a monk or a priest. Sexual intercourse for a devoted to God becomes then an external force which action changes the state of purity and devotion to God. So, before the Catholic church changes its position on the marriage of priests, Newton's first law should be considered because when leaving the vow of chastity to join marriage it is allowing the action of some external force which are wife, children, and some others problems related to family life. These forces constitute now the unbalanced force which will impact their state of devotion or purity to God. It is more interesting when some religious are also apply chastity to an husband and wife as fidelity to each other. When we know that the cause of divorce today is mostly because of infidelity. Family are broken, love suddenly stops when one of the partner is found to the other unfaithful.It is clear that for a couple to remain in constant love there must be no external force that can change their state of perfect love. Infidelity will be perceived as an external force which will change the state of rest or motion of love.
