26 Equally opportune are other admonitions addressed by the Saint to the powerful. Thus, for example, he wrote to Queen Matilda of England: "If you wish in very deed to return thanks rightly and well and efficaciously to God, take into your consideration that Queen whom He was pleased to select for His Spouse in this world. . . Take her, I say, into your consideration, exalt her, that with her and in her you may be able to please God and reign with her in eternal bliss" ( Epist., lib . iii. ep. 57). And especially when you chance to meet with some son who puffed up with earthly greatness lives unmindful of his mother, or hostile or rebellious to her, then remember that: "it is for you to suggest frequently, in season and out of season, these and other admonitions, and to suggest that he show himself not the master but the advocate, not the step-son but the real son of the Church" ( Ibid . ep. 59). It behooves Us, too, Us especially, to inculcate that other saying so noble and so paternal of Anselm: "Whenever I hear anything of you displeasing to God and unbecoming to yourselves, and fail to admonish you, I do not fear God nor love you as I ought" ( Ibid. Lib . iv. ep. 52). And especially when it comes to Our ears that you treat the churches in your power in a manner unworthy of them and of your own soul, then, We should imitate Anselm by renewing Our prayers, counsels, admonitions "that you think over these things carefully and if your conscience warns you that there is something to be corrected in them that you hasten to make the correction" ( Epist., lib . iv. epist. 32). "For nothing is to be neglected that can be corrected, since God demands an account from all not only of the evil they do but also of the correction of evil which they can correct. And the more power men have to make the necessary correction the more vigorously does He require them, according to the power mercifully communicated to them, to think and act rightly . . . And if you cannot do everything all at once, you must not on that account cease your efforts to advance from better to better, because God in His goodness is wont to bring to perfection good intentions and good effort, and to reward them with blessed plenitude" ( Ibid. Lib . iii. epist. 142).
