If you're beating yourself up because your conversion to Catholicism hasn't yet translated into greater peace with your family of origin--don't. Have Hope. Have Patience. Have Humility. But don't go walking around second guessing yourself for not delivering the best Apologetic Defense of the Pope over hor d'oeuvres, or feel like a fraud because a family member gets under your skin.
What Jesus is looking for is growth. Growth is slow, and uneven, and often horribly messy. Trust that your prayers for peace are heard.
