his."[25] Perhaps _he_ had a system of spiritual diagnosis very superior to ours. In the epistle to the Angel of the Church of Thyatira, mention is made of "the woman Jezebel, which calleth herself a prophetess,"[26] who led astray the servants of Christ. St. John surely addresses himself to a community where influences precisely of this kind exist, and are recognised when he writes,--"Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.... Every spirit that confesseth not Jesus is not of God."[27] The Church or Churches, which the First Epistle directly contemplates, did not consist of men just converted. Its whole language supposes Christians, some of whom had grown old and were "fathers" in the faith, while others who were younger enjoyed the privilege of having been born and brought up in a Christian atmosphere. They are reminded again and again, with a reiteration which would be unaccountable if it had no special significance, that the commandment "that which they heard," "the word," "the message," is the same which they "had from the _beginning_."[28] Now this will exactly suit the circumstances of a Church like the Ephesian, to which another Apostle had originally preached the Gospel many years before.[29] On the whole, we have in favour of assigning these Epistles to Ionian and Ephesian surroundings a considerable amount of external evidence. The general characteristics of the First Epistle consonant with the view of their origin which we have advocated are briefly these. (1) It is addressed to readers who were encompassed by peculiar temptations to make a compromise with idolatry. (2) It has an amplitude and generality of tone which befitted one who wrote to a Church which embraced members from many countries, and was thus in contact with men of many races and religions. (3) It has a peculiar solemnity of reference to the invisible world of spiritual evil and to its terrible influence upon the human mind. (4) The Epistle is pervaded by a desire to have it recognised that the creed and law of practice which it asserts is absolutely one with that which had been proclaimed by earlier heralds of the cross to the same community. Every one of these characteristics is consistent with the destination of the Epistle for the Christians of Ephesus in the first instance. Its polemical element, which we are presently to discuss, adds to an accumulation of coincidences which no ingenuity can volatilise away. The Epistle meets Ephesian circumstances; it also strikes at Ionian heresies.
