The Servants of the Pierced Hearts of Jesus and Mary have on their website various pages that link to homilies of certain priests. One of those priests is Fr. Joseph Rogers, pastor of St. John Neumann Church in Gaithersburg MD - my parish. I was unable to attend Mass two Sundays ago. On that Sunday (16th Week of Ordinary Time) he gave a homily on Humanae Vitae. I link to it now.
I'd urge you to both download it and listen to it. It is an excellent homily, especially in light of the fact that we hear so little of that pivotal encyclical. Pray that more priests would speak clearly of this most crucial matter, for the salvation of souls.
