Can Canon 1dx take wedding photos?

I may ask this question because I feel that 1DX pixel is not high. In fact, high pixels are just small pixels. At present, there is no qualitative leap in definition and image quality with high pixels, 24-36 million, but moire may appear.

Canon 1dx can take wedding photos, and it is Canon's top professional camera. Although there are18 million pixels, the whole camera is solidified, and the best picture quality is also beautiful, which is not comparable to the mid-range camera with more than 20-36 million pixels! ? Absolutely no problem!
