One of the other debated issues in the Lord's Supper, in addition to the question of presence, is that of fencing the table. Who may participate? What does it mean to eat and drink unworthily? Who is worthy? Who is unworthy? Calvin takes up these questions in 4.17.40 - 42. He also deals with the question of how it is to be administered in terms of the liturgy of the communion service (4.17.43). Finally, he tackles the question of frequency (4.17.44). All of these questions are worthy of book-length treatments in and of themselves.
Calvin continues his discussion of the errant Roman Catholic view of the sacrament of the Lord's Supper by prattling on about one of his favorite subjects to rail upon: superstition and idolatry. The two, for Calvin, go together like ham and eggs. These practices, in this particular instance the piled on traditions of the adoration of "consecrated host," are repugnant to Calvin because they are extra-biblical (actually, he makes the case that they are anti-biblical) and injurious to the Christian life. How quickly the church can lose its way; how quickly we can lose our way.
"With troubled heart and trembling hand I write.
The heavens have changed to sorrow my delight.
How oft with disappointment have I met
When I on fading things my hopes have set." 
Satan tempts us to compare ourselves to men whom we think are worse than we are.
"You do so much better than Brother Ralph," Satan says:
"Compare yourself to Ralph. You know more theology than he does. You serve God more zealously than he does. You are a little sloppy with your holiness sometimes, but Ralph frequently engages in big sins. You can indulge this small sin and still be far more effective than most Christians. Don't take this one sin so seriously; you'll still be better than Ralph."

Looking for the Lost
Little Bo-Peep has lost her sheep and doesn’t know where to find them;
Leave them alone and they will come home, wagging their tails behind them.
How are God’s people to respond? We remind each other:
- Jesus will never leave us nor forsake us.[i]
