In Christian theology, Jesus is called "the Christ", and "
the Son of God":
441 In the Old Testament, "son of God" is a title given to the angels, the Chosen People, the children of Israel, and their kings. It signifies an adoptive sonship that establishes a relationship of particular intimacy between God and his creature. When the promised Messiah-King is called "son of God", it does not necessarily imply that he was more than human, according to the literal meaning of these texts. Those who called Jesus "son of God", as the Messiah of Israel, perhaps meant nothing more than this.
442 Such is not the case for Simon Peter when he confesses Jesus as "the Christ, the Son of the living God", for Jesus responds solemnly: "Flesh and blood has not revealed this to you, but my Father who is in heaven." Similarly Paul will write, regarding his conversion on the road to Damascus, "When he who had set me apart before I was born, and had called me through his grace, was pleased to reveal his Son to me, in order that I might preach him among the Gentiles..." "and in the synagogues immediately [Paul] proclaimed Jesus, saying, 'He is the Son of God.'" From the beginning this acknowledgment of Christ's divine sonship will be the centre of the apostolic faith, first professed by Peter as the Church's foundation.
In Dharmic terms, Jesus the Christ is also known as the Avatar, the Buddha, the Bhagavan. The Avatar is the descent of the Divine into human form. The Buddha is the awakener, the realizer. Bhagavan is the Blessed One. The Hebraic "son of God" refers to someone with a close relationship to God, and Jesus would certainly fit the bill and more. The Christian "Son of God" refers to someone who has realized his fullness-in-God, to the point of being one with God consciously and embodiedly.
In Dharmic terms, the Son of God would be a Sat-Guru, someone capable of bringing others into the state of fullness-in-God, to the point of being able to confess "I and the Father are One". Many followers of Jesus the Christ believe that Jesus is the Only Son of God; many followers believe otherwise. In any event, the important point is that whichever Sat-Guru would follows, one should be aware of the nature of such a relationship. The Divine Physics of that relationship flourishes in the context of the recognition of the very Divine Incarnation of the Sat-Guru. Sts. Peter and Paul recognized that Divine Incarnation in Jesus. Arjuna recognized it in Krishna, the Avatar. Sariputra recognized it in Siddhartha Gautama, the Buddha. Khadijah recognized it in Muhammad, the Rasul.
Thus, Christianity is based on Guru-Bhakti Yoga, or the Spiritual Practice of Devotion to the Divine-Human Person. Swami Sivananda outlined
some of the laws inherent in Guru-Bhakti Yoga:
1. To learn cooking, you need a teacher; to learn science you need a professor; to learn any art you need a master. Is not Guru necessary to learn Atma-Vidya?
2. Guru indeed is the sole refuge to take you across the Samsaric deluge.
3. On the thorny path of Truth to guide you there is none but Guru.
4. Guru’s Grace can work wonders.
5. In all your struggle of daily life, Guru will guide and protect you.
6. Guru is the torch-bearer of wisdom.
7. Guru, Isvara, Brahman, preceptor, teacher, Divine Master, etc., are synonymous terms.
8. Salute your Guru first before you salute God, because he takes you to God.
9. Take Mantra Diksha from your Guru. This will inspire and elevate you.
10. Guru will not do Sadhana for you. You will have to do it yourself.
11. Guru will show you the right path.
12. Guru can select the right Yoga for the disciple.
13. By Guru’s grace, the disciple can overcome obstacles and doubts on the path.
14. Guru will lift the disciple from the pitfalls and snares.
15. Sacrifice your body and life to serve your Guru. Then he will take care of your soul.
16. Don’t expect a miracle from your Guru to lift you up into Samadhi. Do rigorous Sadhana yourself. A hungry man will have to eat himself.
17. If you cannot get a Satguru you cannot progress in the spiritual path.
18. Be patient and wise in selecting your Guru, because you cannot divorce your Guru afterwards. It is the greatest sin.
19. Relation between Guru and Chela is sacred and lifelong. Understand this point very well.
