The BIBLE says the age difference between couples is a sin….

For our benefit, He was made to bear sin (cf. 2 Cor 5:21), leading the Father to place upon His Son the burden of our transgressions. In the words of Pope Benedict XVI, this act represents a “turning of God against himself” (Deus Caritas Est, 12). God’s love extends even to His adversaries (cf. Mt 5:43-48).

The dialogue that God seeks to establish with each individual through the paschal mystery of His Son is far removed from mere idle talk, reminiscent of the ancient Athenians who “spent their time in nothing except telling or hearing something new” (Acts 17:21). Such trivial conversation, driven by a hollow and superficial curiosity, epitomizes worldliness throughout history; in contemporary times, it can manifest as the inappropriate use of media.
