The Buddha, never said the word "buddhism". He talked about "reality" and walking the eight fold path. He developed a method to work with to attain enlightenment.
But he was a kind of rebel, he discovered his method on his own. He found the shade of a tree and just sat there. He didn't ask a priest or seek a guru. He didn't need to be endowed by any great hierarchy, and in truth, neither do you.
When the Buddha became enlightened, someone said "prove it" he said "I can't, but earth as my witness it is the truth" and he touched the earth.
Each of us need to find a method that works. We can break or follow any rules we like from any established hierarchy. But, in the end, your road will contain things like ; unconditional love, a quiet mind of peace, forgiveness, non-violence, fearlessness , amongst others.
So there is only one method, and at the same time there is no method. You are free to discover it in any way you like. If your heart is pure, God is not that picky.
