[3.] Thirdly, Another sophism of his _is to heighten one duty, to the ruin of another_. He strives to make an intestine war among the several parts of the services we owe to God; and from the excellency of one, to raise up an enmity and undervaluing disregard of another. Thus would he sever as inconsistent those things that God hath joined together. As among false teachers, some say, ‘Lo, here is Christ,’ and others, ‘Lo, he is there;’ so we find Satan dealing with duties. He puts some upon such high respects to preaching, that, say they, Christ is to be found here most frequently, rather than in prayer or other ordinances; others are made to have the like esteem for prayer: and they affirm in this is Christ especially to be met withal; others say the like of sacraments or meditation. In all these Satan labours to beget a dislike and neglect of other services. Thus, in what relates to the constitution of churches, he endeavours to set up purity of churches, to the destruction of unity, or unity to the ruin of purity. A notable example hereof we have in the _Euchytæ_, a sect of praying heretics, which arose in the time of Valentinian and Valens, who, upon the pretence of the commands of Christ and Paul for praying continually, or without ceasing and fainting, owned no other duty as necessary; vilifying preaching and sacraments as things at best useless and unprofitable.[205] The like attempts he makes daily upon men, where though he prevail not so far as to bring some necessary duties of service into open contempt, yet he carries them into too much secret neglect and disregard, Luke xviii. 1; 1 Thes. xv. 17.
