"Listen now how we must pray. The prayer has many qualities.
It is not of no importance of knowing where you must pray, and it is not a question of no importance. The apostle known as: "I want that the men pray in any raising place of the pure hands, without anger and quarrel. " And the Lord says in the Gospel: "when you pray, go into your room and shut the door and pray to your your Fathre". Doesn't it seem to you that there is contradiction? The apostle known as: pray in any place, while the Lord known as: pray inside your room. But there is no contradiction […]. Your room, it is your spirit, Even if you are placed in the medium of the people, you however have in the interior man your closed and secret room [...]
Rather prepare yourself to pray when your heart is pacified. Why irritate you? Your servant made one fault? You prepare yourself to pray so that your own failures are forgiven, and you unworthy against another! It is thus that: prays without anger [...]
. The first part of the prayer must thus contain the praise of God,
. the second the supplication,
. the third the request,
. the fourth the thanksgiving ".
(Ambrose of Milan, the sacraments, 6, 3, 11-25).
