Siemichovia Sophia was a noble Polish lady, whose name Sandius was unwilling to omit, in his list of Antitrinitarian writers, because it was not only upon record, that she had addressed a letter to Faust Socin on the subject of Baptism, but Socin's reply was preserved, and inserted in his published correspondence. She had requested him to interest the Church on this topic ; and the main object of his reply is to shew, that Baptism, however necessary it might be in the infancy of the Gospel, is not now obligatory. He expresses his earnest desire, that the Church may be left free in this matter, because its discussion has been found to impede the course of the Gospel, and he sees that it is daily the cause of much inconvenience, and much scandal ; and that he may not seem himself to minister to this state of things, he makes a point of abstaining from all discussion of the subject, unless he is led into it by the importunity of his friends. Towards the close of his letter he says, "Would that there were many women like you in our Church, who took an interest in sacred things, and in acquiring a more exact knowledge of them, and particularly among those of your own rank and condition, noble matrons, and mothers of many children: for our whole Church might expect to derive thence many advantages. Only proceed in your desire of investigating divine truth, yet in such a manner as to weigh well all the arguments, and scriptural proofs with the greatest patience and gentleness, and above all things to beseech God, that he would open your mind to understand what is contained in his word."
