Other observations of Sikhism include: 1.Not Son of God: The Gurus were not in the Christian sense “Sons of God”. Sikhism says we are all the children of God and by deduction, God is our mother/father. 2. All Welcome: Members of all religions can visit Sikh temples (Gurdwaras) but must observe basic protocols & social courtesies like- cover your head, remove shoes, no smoking or drinking intoxicants.
