When people talk, they lay lines on each other, do a lot of role playing, sidestep, shilly-shally and engage in all manner of vagueness and innuendo. We do this and expect others to do it, yet at the same time we profess to long for the plain truth, for people to say what they mean, simple as that. Such hypocrisy is a human universal. Steven Pinker
As we were baptized, so we profess our belief. As we profess our belief, so also we offer praise. As then baptism has been given us by the Savior, in the name of the Father and of the Son and of the Holy Ghost, so, in accordance with our baptism, we make the confession of the creed, and our doxology in accordance with our creed. Saint Basil
