Praying to God - What are the consequences?

I was raised in a Catholic environment, however I'm adding more and more Dhamma in my life, currently I spend much more time with Buddhists practices than Catholics. the point is that I still keep the habit of praying to God before going to sleep (and before flying too), but if I'm not mistaken this is seen as something bad in Buddhism (wrong view/attachment to rituals) Can someone explain what are the bad consequences, from a Buddhist's perspective of praying to God? If any.
