Well I didn't say that, but now that you mention it: "And when thou prayest, thou shalt not be as the hypocrites are: for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen of men. Verily I say unto you, They have their reward. But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly." (Mat 6:5-6)
You just expressed your Christianty in public.
Well, no I didn't, but big difference between something like evangelizing (expressing your faith in public) and what Cruz is doing.
Matthew 10:32
Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven.
