Buddhism is basically a philosophy; and not really a religion.
That question of whether Buddhism is a way of life, or a religion is hotly debated among Buddhists ourselves.
If you look at Tibetan Buddhism, the form that I practice, it has many of the same "trappings" as the RCC, does. I was raised in the RCC.
We chant in a language other than English, (either Tibetan, Sanskrit or Pali). We have lush displays of art; thangkas of meditational deities, (thangkas are cloth paintings), statues that are consecrated, (filled with holy substances and blessed), candles, incense, flowers, a shrine (which would be called an altar in the west). We wear robes and shawls. We perform prostrations, (just like Muslims do, or Catholics). We have holy days. We have ceremonies, called "wangs" (in Tibetan) "abhisheka", (in Sanskrit) or "empowerments" in English.
Our practices, aka "thun" (in Tibetan) or sadhana (in Sanskrit) follow a specific order:
Taking refuge, generating bodhichitta, (the enlightened intent), seven branch prayer, praises to the meditational deities and lineage masters, visualization, mantra recitation, meditation, non-meditation, dissolving the visualization and offering dedication prayers.
So, is Buddhism a religion or not? It was once the state religion of Tibet. It is the state religion of the tiny country of Bhutan. I would say, yes, Tibetan Buddhism is a religion, but is a non-theistic religion. We don't believe in or pray to a "God". Meditational deities are not gods. They are symbolic representations of subtles states of consciousness that cannot be depicted well in words, but they can be experienced.
Probably this post is too much information.
