One should not seek among others the truth that can be easily gotten from the Church. For in her, as in a rich treasury, the apostles have placed all that pertains to truth, so that everyone can drink this beverage of life. She is the door of life.

St. Irenaeus of Lyon

In going to church, think that you art going to the house of the King of Heaven, where with fear and joy one ought to stand as in heaven before the King of Heaven. While standing in church, do not look around to the sides and do not look at how someone is standing and praying, lest you be condemned with the Pharisee, since you did not come to judge others, but to ask for mercy for yourself from God the Judge and Knower of hearts. Gaze with compunction toward the altar alone, where the holy sacrifice is offered. More than anything else, beware of laughter and conversations, for whoever laughs or converses while standing in church does not render honor to the holy place and tempts others and prevents others from praying.

St. Tikhon of Zadonsk

The rule of piety admits nothing new. All things are to be delivered to those who come after us with the same fidelity with which they were received by us. It is our duty to follow religion, not make religion follow us.

St. Vincent of Lerins

Some people tell me that they are scandalized because they see many things wrong in the Church. I tell them that if you ask a fly, “Are there any flowers in this area?” it will say, “I don’t know about flowers, but over there in that heap of rubbish you can find all the filth you want.” And it will go on to list all the unclean things it has been to. 

Now, if you ask a honeybee, “Have you seen any unclean things in this area?” it will reply, “Unclean things? No, I have not seen any; the place here is full of the most fragrant flowers.” And it will go on to name all the flowers of the garden or the meadow. 

You see, the fly only knows where the unclean things are, while the honeybee knows where the beautiful iris or hyacinth is. As I have come to understand, some people resemble the honeybee and some resemble the fly. Those who resemble the fly seek to find evil in every circumstance and are preoccupied with it; they see no good anywhere. But those who resemble the honeybee only see the good in everything they see. 

The stupid person thinks stupidly and takes everything in the wrong way, whereas the person who has good thoughts, no matter what he sees, no matter what you tell him, maintains a positive and good thought.

St. Paisios of Mount Athos

By the death of martyrs religion has been defended, faith increased, the Church strengthened; the dead have conquered, the persecutors have been overcome.... So, too, David rejoiced in prophecy at the departure of his own soul, saying: ‘Precious in the sight of the Lord is the death of His saints.’ He esteemed death better than life. The death itself of the martyrs is the prize of their life. And again, by the death of those at variance hatred is put an end to.

St. Ambrose of Milan
