Having a dog in this fight, I thought Chelsea Zimmerman covered the topic of the Church and infertile couples with dignity, grace and understanding.
...never forget that no prayers go unanswered and all suffering, given over to the Lord bears fruit in some form. I know that you are hurting, but, I pray the following words of your Holy Father last Saturday can give you at least some small comfort in your pain:
“So I would like to remind the couples who are experiencing the condition of infertility, that their vocation to marriage is no less because of this. Spouses, for their own baptismal and marriage vocation, are called to cooperate with God in the creation of a new humanity. The vocation to love, in fact, is a vocation to the gift of self and this is a possibility that no organic condition can prevent. There, where science has not yet found an answer, the answer that gives light comes from Christ”.Whether you seek to welcome a new member to your family through (ethical) fertility treatment or even the always loving option of adoption, remember that children are a gift, not a right. Keep the focus of your marriage on you and your spouse giving and receiving the total gift self while loving God and trusting Him for the timing of children – if they should ever come.
