"Encourage each other while it is still today" (St. Paul in Hebrews)
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.
