One of the problems with the way society talks about life is that they use the term "quality of life," Wall noted.
"That's such a loaded term," he said. "My quality of life could be different from your quality of life, but that doesn't mean that my life is better or worth more than your life. Every life is worth it and worth living."
"And whether somebody has a disability, whether somebody's old and young, whatever the case is, or if somebody makes a lot of money or doesn't, the quality of life is the same for everyone, (because) our quality of life is we're all created in the image and likeness of God."
Priests should be preaching the truth about Church teaching regarding contraception and human life in order to foster a deeper culture of life among Catholics, Wall added.
"That's something that we shouldn't shy away from preaching - preaching the truth of Humanae vitae, preaching the truth of the theology of the body, preaching the truth of what all the Church teaches when we talk about the sacredness of life," he said.
"And we need to be able to name it for what it is," he added. "So when we talk about abortion, or we talk about contraception, and we talk about embryonic stem cell research, euthanasia, physician-assisted suicide - we call it for what it is. We pray for an end to these intrinsic evils in our society."
Parishes should also give couples who are living according to Church teaching a chance to share their testimonies, Wall said, in order to counter the perception that everyone is using contraception and that it must be okay because it is so widely used.
Wall said he would also encourage Catholics to read Humanae vitae.
"It was a prophetic document from Pope St. Paul VI...because, in terms of the negative things, he said, 'If the Church were to go down this rabbit hole (of approving contraception), these are all the things that we're going to see happen. We're going to see an increase in abortion. We're going to see an increase of violence, sexual acts of violence, sexual acts against women, men objectifying women. We're going to see an increase in divorce.' All these things happened (when) society gave into it."
"But, in the positive sense, Pope St. Paul VI said, 'If we're faithful to God's plan for marriage and God's plans for life, what we're going to see is we're going to see a blossoming of marital life.' So when we see couples that are open to God's plan, what we see is anywhere from a 2 to 4% divorce rate. In other words, we see in 94 to 96% success rate, meaning couples are together. They're being faithful to their marriage vows and staying together 'til death do they part."
Wall added that after his region's ad limina visit, he felt very close to the Holy Father and appreciated his openness to discuss anything.

"We didn't send him a list of questions and have him get prepared for it. He wanted to talk about things. So if you asked him a question, he would sit there and he would really think about it. You could tell he was very thoughtful and very prayerful...and I found that very inspiring. I took away a great love for the Church and a real closeness to him."
