You blame me for not inviting you; and, when invited, you do not attend. That your former excuse was an empty one is clear from your conduct on the second occasion. For had you been invited before, in all probability you would never have come.
Act not again unadvisedly, but obey this present invitation; since you know that its repetition strengthens an indictment, and that a second lends credibility to a previous accusation.
I exhort you always to bear with me; or even if you cannot, at any rate it is your duty not to neglect the Martyrs, to join in whose commemoration you are invited. Render therefore your service to us both; or if you will not consent to this, at any rate to the more worthy.
