Sentence:  On the day wherein we receive the sacrament, we are often over-precise, <WSD>scrupling</WSD> to say or do those things which lawfully we may. But we, who are more than curious that day, are not so much as careful the next; and too often (what shall I say?) go on in sin up to the ancles; yea, our sins go over our heads. 
Meaning of the word marked with <WSD> tags:  To hesitate or be reluctant to act due to considerations of conscience or expedience.
