Do you think it's important for a Filipino couple to get married even though they have been living together for many years now and have three children?

I believe so. My partner& I have been living together for a few years and we already have two girls. Though we're not married yet, we consider ourselves to be but God's blessings through the sacrament of holy matrimony is still needed to strengthen us as a couple and as parents. We still plan to have a church wedding when our finances are more than stable already. Never was it an option to make our parents shoulder the wedding expenses(our reason for not getting married in the first place) nor remain in "living together" status. "Though one may be overpowered, two can defend themselves. A cord of three strands is not easily broken." -Ecclesiastes 4:12, NIV
