No, Mormons try to take advantage of the biblical quote to suit their own false doctrine. People who know God and His truth, as many people on this site do, don't become Mormons.
Milk is not the beginning of Mormonism, and meat is not secret temple ordinances. And people who think they are more worthy than others won't have eternal life.
How exactly do we take advantage of a biblical quote to suit our own false doctrine?
Is that your problem with temple people, they think they are more worthy than non-temple people? It is not that they think they are more worthy, but they do actually apply the gospel of Jesus Christ in their lives and do things that allows them to enter the temple.
For instance: If a man and a woman marry, they promise to be faithful. In a temple marriage, the man and the woman actually covenant with God and Jesus and the HS to be faithful. There is a huge difference that most people are not willing to take upon themselves, and that difference shows up in marriage statistics. Non temple Christian marriages fail at somewhere between 25-35%. Temple marriages in the Church of Jesus Christ can fail also but is closer to 6-12%.
As you can see, covenanting with God and going back month after month to the temple solidifies a marriage because if you fail, you are breaking a covenant with God, not just a promise to a pastor.
There are many things that we do and say in the temple that lends itself to our daily journey towards God. Feeling that we are more worthy than others is not one of those attributes that comes with temple attendance. So if that is how you feel, then again you are wrong about that idea.
Milk and meat are taken in their proper order, and in the Church of Jesus Christ we do it properly. Even doing it properly, many are not prepared to put the meat of the gospel into their daily lives and fall away and are lost, just like the Corinthians in the bible. (1 Corinthians 3:2)
