For me, if you don't practice your religion, you might as well say you're non religious.
Churches are also part of
social networking (parties, neighbors, people of similar backgrounds who won't balk at your ethnic background because they have the same, etc). Sometimes your contacts could get you a
better job.
I have relatives who
attend church/temple, yet openly ridicule people for believing in God. They are scientists and they can't believe that modern people, especially with scientific backgrounds, could possibly believe in some "superstition" that is thousands of years old and backed by scant or nonexistent facts. As far as their preacher/rabbi/guru is concerned, they are devout members of his congregation, little does he know that he has
failed to teach the one thing that is vital to his religion....and that is belief (or faith).
Without faith, all lessons of morality are worthless, because no one is going to follow the teachings without believing. Yet, atheists have their own morality, apart from belief in God. In fact,
atheists seem to be more moral than theists. For example, the Mafia devoutly believes in God, but they also
believe that God will purge them of all sins (so they sin, sin some more, and sin some more, not realizing that only through atonement will they be made pure again). Atonement, of course, means that they will never do it again, and that they were sorry they did it in the first place.
Some religions require marriage to be within their own faith (with the minor exception of conversion to their faith). So, this means that atheist members of their ethnicity can continue to marry into the ethnicity (so their kids won't be of mixed blood). Without faith, that seems almost like bigotry...they won't marry a person who is Black, or Hispanic, or Asian, but must marry someone like themselves.
Oxford Dictionary:
Blasphemy: "The act or offense of speaking sacrilegiously about God or sacred things, profane talk."
It is blasphemy, in my opinion,
to think (not talk) sacrilegiously about God or sacred things. We can assume that God knows not only what we say, but what we think, and even knows our future actions (as long as they are not random....and even then, perhaps God knows).
Some sit in church/temple and think of the preacher/rabbi as a pathetic fool who spent his whole life in pursuit of nonsense. They often voice that opinion to others. To me, that is also blasphemy, since the preacher is just as holy as a sacred thing.
It seems like false advertising to attend church without believing in God. Those who fall in love with you don't know what they are getting into.
My brother attended church for the sole purpose of picking up chicks. He met a lovely woman in church who continued, throughout their marriage, to ridicule his beliefs. His wife was very worried about the relgious upbringing of their daughter.
