Marriage is an original gift from God to humanity. Although sin entered the world damaging the marital relationship, this gift was not lost but redeemed by Christ and raised to a sacrament (see Eph. 5:28-32; see also Mt. 19:4-6). Sacred Scripture proclaims that God created humanity in “His image” as “male and female” (see Gen. 1:27). So unique is this relationship that the marital union makes of the husband and wife “one flesh” (Gen. 2:24). Procreation, Scripture teaches, is a gift from God (Gen. 1:28). When spouses conceive new life, they participate in the Lord God’s creative power. This is an awesome privilege and sacred responsibility!
