This is from the 1928 Book of Common Prayer. We've come a long way in our attitudes.
Dearly beloved, on ___ day next I purpose, through God's assistance, to administer to all such as shall be religiously and devoutly disposed the most comfortable Sacrament of the Body and blood of Christ; to be by them received in remembrance of his meritorious Cross and Passion; whereby alone we obtain remission of our sins, and are made partakers of the Kingdom of heaven. Wherefore it is our duty to render most humble and hearty thanks to Almighty God, our heavenly Father, for that he hath given his Son our Saviour Jesus Christ, not only to die for us, but also to be our spiritual food and sustenance in that holy Sacrament. Which being so divine and comfortable a thing to them who receive it worthily, and so dangerous to those who will presume to receive it unworthly; my duty is to exhort you, in the mean season to consider the dignity of that holy mystery, and the great peril of the wunworthy receiving thereof; and so to search and examine your own consciences, and that not lightly, and after the manner of dissembers with God; but so that ye may come holy and clean to such a heavenly Feast, in the marriage-garment required by God in holy Scripture, and be received as worthy partakers of that holy Table.
The way and means thereto is: First, to examine your lives and conversations by the rule of God's commandments; and whereinsoever ye shall perceive yourselves to have offended, either by will, word, or deed, there to bewail your own sinfulness, and to confess yourselves to Almighty God, with full purpose of amendment of life. And if ye shall perceive your offenses to be such as are not only against God, but also against your neighbours; then ye shall reconcile yourselves unto them; being ready to make restitution and satisfaction, according to the uttermost of your powers, for all injuries and wrongs done by you to any other; and being likewise ready to forgive others who have offended you, as ye would have forgiveness of your offences at God's hand: for otherwise the receiving of the holy Communion doth nothing else but increase your condemnation. Therefore, if any of you be a blasphemer of God, an hinderer or slanderer of his Word, an adulterer, or be in malice, or envy, or in any other grievous crime; repent you of your sins, or else come not to that holy Table.
And because it is requisite that not man should come to the holy Communion, but with a full trust in God's mercy, and with a quiet conscience; therefore, if there be any of you, who by this means cannot quiet his own conscience herein, but requireth further comfort or cousel, let him come to me, or to some other Minister of God's Word, and open his grief; that he may receive such godly counsel and advice, as may tend to the quieting of his conscience, and the removing of all scruple and doubtfulness.
