I find the Popcak's podcasts encouraging and interesting. I have learned more about myself and how to be graceful and charitable in my relationships by listening to their program. They are faithful Catholics helping us to live Church teaching in practical ways.
Greg and Lisa are fantastic! Better, more solid, Catholic advise you will not find anywhere else. They take the Theology of the Body and apply it not only to you marital relationship, but to parenting as well.
