There is no contradiction between true religion and science. When a religion is opposed to science it becomes mere superstition: that which is contrary to knowledge is ignorance.
How can a man believe to be a fact that which science has proved to be impossible? If he believes in spite of his reason, it is rather ignorant superstition than faith. The true principles of all religions are in conformity with the teachings of science.
The Unity of God is logical, and this idea is not antagonistic to the conclusions arrived at by scientific study.
All religions teach that we must do good, that we must be generous, sincere, truthful, law-abiding, and faithful; all this is reasonable, and logically the only way in which humanity can progress.
All religious laws conform to reason, and are suited to the people for whom they are framed, and for the age in which they are to be obeyed.
The spiritual part never changes. All the Manifestations of God and His Prophets have taught the same truths and given the same spiritual law. They all teach the one code of morality. There is no division in the truth. The Sun has sent forth many rays to illumine human intelligence, the light is always the same.
The practical part of religion deals with exterior forms and ceremonies, and with modes of punishment for certain offences. This is the material side of the law, and guides the customs and manners of the people.
In the time of Moses, there were ten crimes punishable by death. When Christ came this was changed; the old axiom 'an eye for an eye, and a tooth for a tooth' was converted into 'Love your enemies, do good to them that hate you', the stern old law being changed into one of love, mercy and forbearance!
In the former days the punishment for theft was the cutting off of the right hand; in our time this law could not be so applied. In this age, a man who curses his father is allowed to live, when formerly he would have been put to death. It is therefore evident that whilst the spiritual law never alters, the practical rules must change their application with the necessities of the time. The spiritual aspect of religion is the greater, the more important of the two, and this is the same for all time, it never changes! It is the same, yesterday, today, and for ever! 'As it was the beginning, is now, and ever shall be.'
