Extremely true, as they both speak of one God. They both have rituals and dogmas. Christianity has a Messiah or Saviour, which is called Christ. Hinduism has a few : Krishna, Rama, etc. Not Saviours in the true sense, but men and women of God as direct descendents, in order to manifest the Supreme and bring in a Higher Truth.
Hinduism speaks of Brahman as the Absolute Reality, the equivalent of the Christian God. They have many 'gods' which are simply aspects of Brahman, but Hindu's do not help, in so far as they speak in such a way as to encourage Christianity to believe that they have many Gods. Not true. One Brahman or God is common to Hinduism. Christianity has its numerous angels and arch-angels and Hinduism has its 'gods'
Hinduism is universal. It believes in the immortality of the soul and evolution through the process of reincarnation and the law of Karma. To them, all Souls are immortal and all are God's children and prophets are essentially from the same stream, even though they vary their message to suit the particular century. Christianity speaks of Christ as the only Saviour.
The Christian scriptures, however, speaks of retribution and compensation and a whole list of things you will easily find in the doctrines of Confucious or even the Buddha's Dharmapada. Christianity uses the rosary to say its japa or mantra, and the Hindus speak of mantras and japa mala. Both are essentially doing the same thing in different ways.
My take is that all have a common ground and all are essential. One man needs the ritual and the prayers or puja, just as much as the other needs his meditation. The spiritual ladder has many rungs, and, like the baby, we all have to grow. I do not know of anything in creation without its usefulness. Creation comes from God/Brahman/Allah. There is nothing outside of that Perennial Entity (God) and all things have their usefulness and purpose.Loving thoughts.
