Congregation

Catholics teach that believers and unbelievers were baptized in the red sea crossing, they include the babies of course. Yet, in many cases the laws of God applied to the congregation.

The congregation was commanded to sacrifice and eat of the Passover, which is something infants could not do

Exo 12:3  Speak ye unto all the congregation of Israel, saying, In the tenth day of this month they shall take to them every man a lamb, according to the house of their fathers, a lamb for an house:

Exo 12:4  And if the household be too little for the lamb, let him and his neighbour next unto his house take it according to the number of the souls; every man according to his eating shall make your count for the lamb.

In speaking to the congregation the infants were excluded from the count, they could not understand, and excluded in counting their number. They could not understand or do the word given by Moses by eating. It seems the word congregation meant those who could willingly join themselves together. It was those who could willfully eat. The commands were for those who could comply.

In Judaism they are required to keep the commandments at age 13 for males, but could keep the commandments earlier by choice.

Not all who crossed the Red Sea were part of the congregation. Babies were not counted. They were not counted until old enough to come and hear.

Exo 16:10  And it came to pass, as Aaron spake unto the whole congregation of the children of Israel, that they looked toward the wilderness, and, behold, the glory of the LORD appeared in the cloud.

We know that all who crossed the Red Sea who were old enough to be counted believed.

Exo 14:31  And Israel saw that great work which the LORD did upon the Egyptians: and the people feared the LORD, and believed the LORD, and his servant Moses.

It says all Israel believed at the time of the crossing, for they saw the waters parted firsthand.

In their baptism they were brought to belief, just as in teaching baptism, people hear the Gospel and believe. In baptism we teach believers and unbelievers, but at the time of baptism they have come to belief through the teaching.

The Catholic claim that believers and unbelievers passed through the sea is false. Babies were not counted in the congregation. All those who crossed believed during the process and immediately after.

Even those who wanted to return to Egypt before the waters were parted came to belief as they saw the waters parted and the way became dry.

Exo 14:10  And when Pharaoh drew nigh, the children of Israel lifted up their eyes, and, behold, the Egyptians marched after them; and they were sore afraid: and the children of Israel cried out unto the LORD.

Exo 14:11  And they said unto Moses, Because there were no graves in Egypt, hast thou taken us away to die in the wilderness? wherefore hast thou dealt thus with us, to carry us forth out of Egypt?

Exo 14:12  Is not this the word that we did tell thee in Egypt, saying, Let us alone, that we may serve the Egyptians? For it had been better for us to serve the Egyptians, than that we should die in the wilderness.

Exo 14:13  And Moses said unto the people, Fear ye not, stand still, and see the salvation of the LORD, which he will shew to you to day: for the Egyptians whom ye have seen to day, ye shall see them again no more for ever.

Exo 14:14  The LORD shall fight for you, and ye shall hold your peace.

God knew they would be quited when seeing his power. They disbelieved before the parting of the water but became confident after it was parted.

Heb 11:29  By faith they passed through the Red sea as by dry land: which the Egyptians assaying to do were drowned.

Another example of the congregation excluding infants is

Num 15:35  And the LORD said unto Moses, The man shall be surely put to death: all the congregation shall stone him with stones without the camp.

Babies can't stone people. The context is those of a little age.

In Judaism people are not required to keep the commandments until age 12 or 13.

So what does it mean to become a bar mitzvah? Under Jewish Law, children are not obligated to observe the commandments, although they are encouraged to do so as much as possible to learn the obligations they will have as adults. At the age of 13 (12 for girls), children become obligated to observe the commandments. The bar mitzvah ceremony formally, publicly marks the assumption of that obligation, along with the corresponding right to take part in leading religious services, to count in a minyan (the minimum number of people needed to perform certain parts of religious services), to form binding contracts, to testify before religious courts and to marry.
