I think it is perhaps the other way around. When one looks at the likes of the Desert Fathers, St. Herman of Alaska, St. Seraphim of Sarov, St. Benedict, the "fools for Christ", and countless others, it is the Christian life lived that becomes the vehicle of witness. I think that is all too often overlooked in our age of bullet points, agendas, conference calls, programs and ministries.
I think first our own house has to be in order, ourselves and our families in the domestic church. Then we go from there. If you can pray with and pass on that witness of the One, Holy, Catholic and Apostolic Faith to your children, a mighty seed has been sown.
Not only is the family, the domestic church, a microcosm of the universal Church, but when prayer, love, and communion of faith are lived out in that family, a living icon of the heavenly realm as well.
I think in this current age of "validation", unless we are seen actually doing what we say first, then little good fruit will be realized.
