Nevertheless, we know that a man named Valentine who lived in the 3rd century was a Christian martyr. Hence we celebrate St. Valentine's Day as the day of love. Love in the 21st century is a colossal concept that means different things to different people. The modern world has adopted a notion of love that is contrary to the love taught and modeled by Jesus Christ and true Christian charity. Let me humbly attempt to contrast biblical love and modern love in terms of contemporary love relationships and in the context of marriage.
Modern love is based on experience.
This leads to love being defined by feelings. This type of love cannot be controlled. Therefore, love or lack of love is not a moral issue. Seeing and feeling is believing. I must be attracted enough in order to elicit a love response.
