How can God not be a magician if Jesus' conception was supernatural?

To create more humans a member of the female sex has to copulate with a member of the male sex. The man's sperm fertilities the egg and an embryo develops in the females womb and this is natural. I do not know how each denomination interprets Mary's virgin birth within the Christian faith. If Mary gave birth to Jesus as a virgin how can this *not* be considered supernatural as well as in the realm of magic? But the Catholic Pope Francis said that the Christian God is not a magician. There are also examples of testimony that Jesus performed miracles outside of the natural order. I know I have asked [a similar question](https://christianity.stackexchange.com/q/101757/10672) about God's omnipotence but these testimonies come into conflict with the Catholic Church's position upon the power of God. My intention is not to criticize the Christian faith at all. On the other hand, these questions come out of respect for the existence of God. So are there denominations of the Christian Faith that still believe that God has unquestionable power?
