Is Perfect Love a Special Charism?

We find in some honest minds a theoretical difficulty which constitutes a stone of stumbling in the way of their seeking full salvation. It is the notion that the grace of perfect love is of the nature of a charism, or special gift of the Holy Ghost, dispensed by the Father according to his own will, and hence not attainable by all believers.

Are there not instances in which the fullness of the Spirit, or perfect love, is dispensed in a sovereign manner without compliance with the usual conditions? We dare not say that there are not; for (1.) We read in the Scriptures of one who was to be filled with the Holy Ghost from his mother's womb. (2.) We believe that the souls of infants, defiled by inborn depravity, are, without faith on their part, entirely cleansed before death by the blood of sprinkling because they are included in the new covenant which is ratified by that universal atonement which saves all souls which do not willfully reject it by unbelief. (3.) For the same reason we believe that all justified souls, all persevering believers in Jesus Christ, who, through imperfect apprehension of the "exceeding greatness of his power" to save to the uttermost," are painfully conscious that they are not cleansed from all inward unrighteousness, are, before death, entirely sanctified by the sovereign will of Him who stands pledged "to finish the good work which he has begun" in them, and "to present them faultless before the presence of his glory with exceeding joy "
