I do not doubt that all those who have received Baptism anywhere and from whomever do have Baptism, as long as it was consecrated with the words of the Gospel and they received it without pretence on their part and with some degree of faith. However, it would not avail them for their spiritual salvation if they were lacking in that charity by which they might be implanted in the Catholic Church.
Saint AugustineIn what is necessary, unity; in what is not necessary, liberty and in all things charity.
Saint AugustineTo seek the greatest good is to live well, and to live well is nothing other than to love God with the whole heart, the whole soul, and the whole mind: It is therefore obvious that this love must be kept whole and uncorrupt, that is temperance; it should not be overcome with difficulties, that is fortitude, it must not be subservient to anything else, that is justice; it must discriminate among things so as not to be deceived by falsity or fraud, that is prudence.
Saint AugustineFor you [God] are infinite and never change. In you "today" never comes to an end: and yet our "today" does come to an end in you, because time, as well as everything else, exists in you. If it did not, it would have no means of passing. And since your years never come to an end, for you they are simply "today."
Saint Augustine
