In our Catholic faith we believe in the resurrection of the body. The Scripture states that in the kingdom there is neither male nor female. Does this mean that our body will not be resurrected in its full earthly form?
It seems that you're referring to what Paul writes in Galatians 3:28 There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus.
Here St. Paul is indicating that there is no difference in terms of dignity. In other words, whatever distinctions there are between us, even essential distinctions, there remains the truth that we are all equal in dignity before God, whose children we are.
But this equality in dignity does not mean there is no difference in essence. Clearly, being male or female is a distinction that goes to the very depths of our being, including our soul. And thus, when our body rises, we will indeed be male or female.
Perhaps, in the context of your question, it is also good for us to reflect on a common modern error that reduces sexual distinctions to a merely incidental, surface quality about the physical characteristics of the body. But this is not so. The soul is the form of the body. That is to say, it is the identity of the soul and its capacities that give rise to the design of the body. Hence, a person’s sex is not simply an incidental quality of their body, but is an aspect of their person that extends from the depths of their soul. Human persons do not just have a male or female body, they are male or female.
The most extreme form of reducing sex to a merely incidental quality of the body, is illustrated in those who engage in so-called "sex change" operations, as if simply altering the body surgically could change a person's sexual identity. It cannot. Scripture says, God made them, male and female He created them. (Gen 1:27). Our identity as male or female extends to our inmost being, and cannot simply be shed like clothing is.
Hence, when we rise, we will indeed be male and female. Further, even before the resurrection of the body, our soul remains male or female.
