Celibacy (especially in relation to deacons) was the topic under discussion here. Your previous reply to me had moved into a number of different areas (i.e., different 'rights', different 'vocations'). 
That was where you "strayed".
'Stray' - meaning 'to become distracted from an argument or train of thought'.
In fact, I now see that your previous reply had strayed completely from the matter under discussion, without returning to it at all. 
However, you did write it in comprehensible English, which was a step forward from your prior effort:-  "We are given rights to effect duties from our nature or from our vocation".
