Christianity

Again, consider how much the principles of the religion of Christ have been forgotten, and how many heresies have appeared. For example, Christ forbade revenge and transgression; furthermore, He commanded benevolence and mercy in return for injury and evil. Now reflect: among the Christian nations themselves how many sanguinary wars have taken place, and how much oppression, cruelty, rapacity and bloodthirstiness have occurred! Many of these wars were carried on by command of the Popes. It is then clear and evident that in the passage of time religions become entirely changed and altered. Therefore, they are renewed.

So Christ said, "Be ye therefore perfect, even as your Father which is in heaven is perfect," meaning that perfection is the requirement of Christianity. Be the image and likeness of God. This is not easy. It necessitates the focalization of all heavenly virtues. It requires that we become recipients of all the perfections of God. Then we become His image and likeness. For in the Bible it is stated, "Let us make man in our image, after our likeness." The attainment of this is most difficult.

When Christ appeared with those marvelous breaths of the Holy Spirit, the children of Israel said, "We are quite independent of him; we can do without him and follow Moses; we have a book and in it are found the teachings of God; what need, therefore, have we of this man?" Christ said to them, "The book sufficeth you not." It is possible for a man to hold to a book of medicine and say, "I have no need of a doctor; I will act according to the book; in it every disease is named, all symptoms are explained, the diagnosis of each ailment is completely written out, and a prescription for each malady is furnished; therefore, why do I need a doctor?" This is sheer ignorance. A physician is needed to prescribe. Through his skill the principles of the book are correctly and effectively applied until the patient is restored to health. Christ was a heavenly Physician. He brought spiritual health and healing into the world. Bahá’u’lláh is, likewise, a divine Physician. He has revealed prescriptions for removing disease from the body politic and has remedied human conditions by spiritual power.

When Christians act according to the teachings of Christ, they are called Bahá’ís. For the foundations of Christianity and the religion of Bahá’u’lláh are one. The foundations of all the divine Prophets and Holy Books are one. The difference among them is one of terminology only. Each springtime is identical with the former springtime. The distinction between them is only one of the calendar -- 1911, 1912 and so on. The difference between a Christian and a Bahá’í, therefore, is this: There was a former springtime, and there is a springtime now. No other difference exists because the foundations are the same. Whoever acts completely in accordance with the teachings of Christ is a Bahá’í. The purpose is the essential meaning of Christian, not the mere word. The purpose is the sun itself and not the dawning points. For though the sun is one sun, its dawning points are many. We must not adore the dawning points but worship the sun. We must adore the reality of religion and not blindly cling to the appellation Christianity. The Sun of Reality must be worshiped and followed. We must seek the fragrance of the rose from whatever bush it is blooming -- whether oriental or western. Be seekers of light, no matter from which lantern it shines forth. Be not lovers of the lantern. At one time the light has shone from a lantern in the East, now in the West. If it comes from North, South, from whatever direction it proceeds, follow the light.

The Bahá’ís should try to study history anew, and to base all their investigations first and foremost on the written Scriptures of Islam and Christianity.
