Thank you, Nadir.
When asked where he got the idea, he said that the laborers around him advised him to get married and have a child to take care of him in the future. I tried to explain to him that it would be difficult for his future wife to budget his meager income and then she might be tempted to use products against pregnancy which would be sinful. He then said he would not want to commit sin but when I asked him what he would do if his future wife would insist on contracepting, he answered that he would leave her. When I reminded him that divorce is not an option for Catholics, he didn't want to continue our conversation.
On another occasion, I pointed out to him the priest and said that some men are called by God not to marry and such people who respond to God's call do not worry about who will take care of them in their old age because God does not abandon the people who put their trust in Him. He was silent. I shared to him the story of St. Andre who helped so many people by dedicating his whole life to taking charge of the sacristy and the doors of the church. He smiled and said he still wanted to get married.
Then another time, he said that he will just wait to know the will of God.
But recently, whenever I see him all excited and dressed up and ask, "do I know her?", he would just smile very broadly.
I have known him and his brothers, sisters and cousins for years, and we're like family already. I pity his condition because he really doesn't understand much but he has strong muscles from years of hard labor. An equally intellectually-challenged girl may get attracted to him and I wonder how a contract between "forever young" minds could be valid.
