Father Malachi Martin, makes it clear. It's in regards to eternal things. I think he stated, "What is worse a nuclear war that lasts a short time? or spending your eternity in Hell? He tells people to keep the faith, pray the rosary everday, and stay in a state of grace free from mortal sin. Interestingly, he made a clear point that the primary purpose for the marriage act is to create children, and the secondary aspect of that is marital intimacy. Grave sin is all around and becoming acceptable to people more and more. Our Lady at Fatima stated to the children that more souls are lost due to sins of the flesh than all other reasons.
